Hey Gang, I have searched for this answer and have found a lot of info about heavy recoil springs in Kahr pistols BUT have never found the answer to WHY Kahr uses such heavy springs even on 9mm guns? Do they need that much spring to chamber rounds or what? (Anyone)?.. Thanks in advance for your thoughts...

One reason that Kahr uses heavier recoil springs is to reduce muzzle flip and felt recoil.

The smaller size and low mass means there is a lot of recoil and the frame is going to take a hell of a beating. Heavy spring counteracts the recoil. Most small pistols have heavy recoil springs and those that don't usually have a short life from the beating they take.

what muggsy and bug[plat stated is about right to.
one adjusts to the strong springs on a kahr, just takes alittle time with the gun but after awhile u don't notice it like u did at first for now when you grasp the slide the body has already trained itself to adjust to the object you have in ur hand. Kahrs will loosen up somewhat in the spring category but they will never get to be like a glock. Heavier springs can go alot longer also, I think the Rohbaur R9 recommends recoils spring changes every 200 rounds. I always felt one reaosn for that was their gun is so small that to put stiff damn springs in would be a detriment to selling it, so they put in pu-sy springs that do the job but just don't last long. I guess kahr could have taken that same road but I don';t think we would like reading in our manual that one should change springs every 200 rounds.

As a rule of thumb, the lighter the slide- the higher the spring ratio. The heavier spring is one reason the guns are +P rated and were originally +P+ rated. Lower spring weights are available if you want. You can safely go to 16# and the gun will still work.

Cutting a coil or so off the big spring can lighten it up a bit, too.

at one time introduced the "lady" kahr PM9 is was merely the same gun with 16# recoil springs, so indeed ur right. Wollfs I think even makes 16# springs for the old style PM9.:behindsofa:

Could that be a viable option after a few hundred rounds break in, shooting just enough rounds to confirm proper functioning with the lighter spring, and then no more than 50 rounds at the range every now and then to keep gun and shooter tuned up? (I am not a hundreds or thousands of rounds per year shooter normally, unless I am breaking in one of these Kahrs. :tongue:) And would those springs work in the CM9? Or should I experiment with taking a coil or 2 off? And should the coil trimming be done on a new spring before it has taken a set?
The reason I ask is to aid in hand racking with my very crippled hands. I love my CM9, but I need a solution for hand racking and being able to do the tap and rack to clear a jam. If my gun can function with a lighter spring, even if I have to replace it more frequently, it would be a great win for me.
PS: I could use a low recoil load such as Critical Defense or standard pressure loads to compensate for the weaker spring, couldn't I?

If the heavier spring is used to reduce recoil and flip, could I reduce it even more by putting in an even heavier spring?
If so, what's the heaviest spring I can put in my CM?
One reason that Kahr uses heavier recoil springs is to reduce muzzle flip and felt recoil.
Not entirely true. There is a narrow range of spring tension that that will work. As parts get lighter as on Kahr pistols it becomes very narrow. On full size guns like a 1911 its less critical because of the greater inertia of the heavier parts. The slides speed must be regulatef to allow feeding and to prevent unduee wear.
More... Think in terms of cartridge rise time and battering.

Partially incorrect in a handgun application.
Spring rate is determined by wire diameter, diameter of the spring and the number of active coils.
A handgun recoil spring begins partially compressed and usually has several inactive coils, especially on "one end closed" springs like Kahr uses.
You have to trim several coils to alter the spring rate. Trimming that many coils would make assembly difficult due to the spring not being "captured" between the barrel lug and the slide.
Basically, if you trimmed enough coils to alter the rate you wouldn't be able to assemble the gun.

Can I run a 20.5#, extra power spring from Wolff that shows to be for the PM9 & PM40 in my CM9?
If so, will it reduce felt recoil or what is the purpose of an extra power spring?
Just trying to learn something here. Thanks!

I don't know that I could honestly say I've ever noticed a change in recoil by going to a higher force spring, but I do it mainly to slow the slide down, in order to allow use of higher pressure ammo without causing accelerated wear and tear.

Felt recoil is purely subjective.
The actual recoil force is the same no matter what spring you have installed (physics 101) but how that recoil feels can be altered with spring rates.
I don't tune my guns for recoil, I tune them for reliability.
I've found the stiffer recoil spring to be more reliable in feeding, with felt recoil having more push but less snap.

I understand that the force exerted would remain constant, for the most part and assuming your ammo remained constant. But I guess I was thinking about it like the shock absorbers on my car. The amount of jolt I felt would be different as the type of shock absorber changed from regular to heavy duty to whatever.
The force exerted on the car could/would remain the same, but what I 'felt' would change as I changed the shocks. Are recoil springs just so small and have such a great force of them that I wouldn't notice?
If so, then am I correct in thinking that the primary, maybe only, benefit of changing the recoil spring is to run hotter ammo, more reliably, through my pistol?
As I type that though, I don't think it could be right. Surely a heavier recoil spring would also help dissipate the energy better and help me get back on target quicker?
Does any of this make sense or am I just 'blowing smoke'? :)

I have no complaints about it at all. Really like my CM9. Glad I found this site and was steered in that direction because of it. Just thought it might give me a little bit of an edge when firing multiple rounds and was willing to try it. If I have to wait to do so, fine. But I am also fine if it doesn't work out that I even get to try it.
This stuff is interesting to me anyway and good to know.

Has anybody found a lighter 16lb spring made for the CM9?
I bough my CM9 last week. I also have a crippled hand. I am planning to make a slide racker for it but really also need a lighter spring.
JFootin

You might check with Wolff Springs to see if they have some lighter springs for the PM9 that might work, but I don't think there is anything available. I have crippled hands and racking is a definite issue with my CM9. My weak hand is more crippled, so I have to switch hands and rack the slide using my strong hand. My slide is mirror polished and my grip is so weak that I sometimes have to put on a rubber glove to get a good enough grip. I also use an empty mag to lock the slide open because there is no way that I can reach a thumb over and do that while holding the slide back.
Funny thing, though. When I had to clear a jamb at the range awhile back, I was able to rack the slide on the warm gun with no problem. So maybe I would be able to handle it in a s.h.t.f. situation. But doubts about my proficiency with it have prompted me to carry it less often. I love my shiny mirror polished CM9, even if it becomes a safe queen. :p
http://i1230.photobucket.com/albums/ee486/John_England/My%20Custom%20CM9/KahrCM9PolishedLSwMagandBullets.jpg
I was also prompted to look at some other options. I bought a S&W J frame and got a trigger job done on it, reducing the DA pull from an impossible 11 lbs to 4.25 lb. Before modification, I could not pull it at all. Now, I love this gun and it is my favorite carry gun!
http://i1230.photobucket.com/albums/ee486/John_England/Miscellanious%20Guns%20and%20Holsters/My638.jpg
The other option that I have pursued is to get a larger gun with an easier to rack slide, plus the added benefits of higher capacity and longer barrel and sight radius. I had about settled on a Glock 19 (and I found a great deal if anyone wants to know), but it would be a compromise holding that 2x4 in my small hand. If your hands aren't small like mine, the G19 would be a viable option. And the slide is easy to rack. Tons of accessories are available, including a cocking assist ring. I got sidetracked when I went to the range with my shooting buddy and helped him put rounds through his new Caracal C (http://www.caracal.ae/new/caracal-c.php), which is the same size and capacity (15) as the G19, but has a rounded, ergonomic grip that works way better for my small hand. The gun also has an incredibly low bore axis which reduces muzzle flip and felt recoil to a minimum. The build quality is extremely high, recoil spring life is 10,000 rounds, the trigger is light and smooth and it is a tack driver! The icing on the cake is that I can rack the slide easily without swapping hands! :cheer2: So, I am taking the plunge on one.

Two questions;
1. What is a cocking assist ring?
2. When did Karh go from an old style spring to a new style spring? My Kahr PM9 is less than a year old and yet I have the old style (13 curls). I'm not complaining (I love my PM9) I'm just curious.

As I understand it, they changed springs when they restyled the front end of the PM9, which slightly lengthened the barrel and slide, back in the mid-2000s. The number of curls seems to be all over the place with no rhyme or reason.

Pretty gun JF. I've got a Glock 17 and 34. I don't have any problem racking those. I do have a slide racker that replaces the back cover on the slide on my 34 that I shoot IDPA with. Instead of the finger hole style in your pic it's a flat piece of metal that sticks out a little less than a quarter of an inch on each side of the gun and makes it a lot easier to hold the slide open to show all clear after I finish shooting a scenario.

Well, I found the Caracal to be very easy to rack. In fact, I could rack it with my weak hand and not swap hands like I have to do with my CM9 and TCP. But the hands are slowly getting worse, so I might try one of those ring shaped handles. The Glock slide is 1.18" wide and the Caracal is 1.10236" wide. 0.07764" narrower. But the handle tightens with a screw and I'll bet it could take up the slack. I like that ring shape because it would be comfortable carrying the gun on my waist with nothing digging into my side.

I agree the ring seems to make more sense for ccw.
I called Wolf Springs today. The tech was nice, but simply stated that the computer didn't show any springs at all for the CM9. So much for a reduced recoil spring.
Maybe I'll order an extra spring from Kahr and try cutting it down a coil.?.

1) That mirror polish on your CM9 is sexy!!!!
2) I have weak hands too. From my experience, the hammerless designs are impossible for me to rack. It's a fluke that I can even rack a CM9/PM9, but even then, I could not rack mine at first until I reached close to 150 rounds. Now I can but it's still a little stiffer than I'd like, although I think after another 100-200 more rounds it will be even better. My recommendation to anyone with weak hands like mine: either buy a revolver or go for the external hammer designed semi autos. I have a much easier time racking those before break in, and afterwards they are perfect. Also, make sure the slide serrations are nice and deep, and not too far spaced. If they don't bite into your fingers well enough, you can't get a good enough grip to pull the slide back. Just my experiences.
3) I wish I'd heard of that Slide Pull Charging Handle back when I still had my Springfield XD!! That might have made a big difference in my ability to rack that slide. Good gun, just way too stiff for my hands, even after break-in. Oh well, I tried.

We should have traded guns!
I bought a PM9 for my wife. It was one of the few nines that fit her, ergonomically. The single stack and short trigger reach was just right. But, she could NOT rack the slide.
After another trip to the LGS and trying on everything for size, she settled on an SA XDM. She has no problems with the slide at all. This afternoon, we were at the range, and I noticed she was using the slingshot technique to chamber the first round. She still can't rack the slide on the PM9.

I have about 250 rounds through my CM9 and the slide is still almost impossible for me to rack. This is complicated by the slick finish - it is hard to grip. But, WTH, the gun is 100% reliable and I don't carry extra mags with me, so I am confident that I have 7 that will go bang when I need them. It is forget about it comfortable in the PJ Holster at 8:00 all day long. The perfect carry gun. And a worthy safe queen if I decide not to carry it. I love that sexy babe! :D
That said, I got the S&W 638 with the 4.25 LB trigger job so I can carry 5 that go bang every time without any slide to rack as my hands get worse.
But look at my next fine addition: a high capacity, double stack pistol with a 4" barrel and erogonomics to die for - a Walther PPQ (http://www.smith-wesson.com/webapp/wcs/stores/servlet/CategoryDisplay?catalogId=13152&storeId=10002&categoryId=769157&langId=-1&parent_category_rn=43326&top_category=43326), which I will have in my hands in about 3 weeks!

That slide is easy to rack, plus it has all of those large serrations on the front and rear of the slide. Weight is just 21.7 oz w/o mag. The trigger is like an expensively customized and lightened Glock trigger. It has 3 dot sights that are adjustable front and rear. The grip is very ergonomic and favors smaller hands like a Glock or SD won't. The slide lock and mag release are ambidextrous, which I like being a lefty. ;)
I have had my eye on the PPQ for a long time now, but they are almost impossible to get new unless you are willing to pay way too much for one on Gunbroker or GunsAmerica. Used guns just aren't available because owners love them and won't sell or trade them. Walther says they cannot keep up with the demand for them. Yesterday, as I have done for months to no avail, I was going through my bookmarks folder of online dealers to see if I could find any in stock, half asleep, not expecting to find anything. But I ran the search at Grabagun.com and, glory be, it said there was exactly 1 in stock, at a good price! I called them immediately to confirm the availability, and when they checked and said yes, I said I'd take it! I actually didn't have the money to purchase it outright. But they have a layaway plan, so I put a down payment on it.
I am elated! :D Three weeks until I can pay it off and have the gun in hand. This gun and a couple of holsters are my birthday and Christmas presents to myself this year! Happy holidays! :third:

Here are some posts from Firearms Blog about the PPQ:
Just bought a PPQ after considerable research including hands-on evaluations. Originally I was looking at the Smith and Wesson M&P Pro.
Trigger action is awesome. Mine was measured by the gunsmith and has a 4.5 lbs trigger pull out of the box with no modifications! The trigger is like a single action since the pre-tensioned trigger results in the first round trigger pull having the same trigger weight as subsequent pulls. The trigger action is smooth with a .1 inch reset (2.54mm). The magazine release lever(s) is awesome once you adapt to it. It can easily be activated without having to disturb your trigger finger or stance allowing you to hold the weapon in position on quick magazine reloads. There are no tools required for a take down, but unfortunately, you will need a punch and small hammer to punch out a pin if you need to change the back-strap. The medium is installed by default so I decided to try the other sizes out and ended up choosing the small backs-trap. I purchased the ppq for range and day time competition use, so I replaced the front sight with a green fiber optic site and for now I am keeping the factory rear site with a planned upgrade to an LPA fully adjustable rear site.
Gentlemen –
I have owned this gone for over a month now and it is fantastic. Mag release is awesome, slide release is awesome and it’s a great shooter. Advantages over the Glock? Controls that are actually easy to use. I never understood a tiny slide release that you could not get your thumb on. Then something other then a tiny 1/4 inch button on one side of the gun for a mag release. THe mags are also metal instead of plastic – a huge issue with the glock in my opinion. A metal Walther mag doesn’t stick or swell.
As fas as the aesthetics, I think the gun is gorgeous, easy to maintain and easy to carry. I wanted a P99 QA but could not get one. When I saw the PPQ, I got really exited and when it was available, I went for it. Only one thing lacking – a more competitive minded model like the Glock 34 or HK P30 L. I wish hey made one with a 5 inch barrel.
Was in Germany recently and it looks like their policia are now using the ppq.Here is a quote from a review (http://www.ammoland.com/2012/03/14/walther-ppq-9mm-handgun/) at Ammoland:
He went on to tell me that it was a Walther PPQ and has the most amazing factory trigger he has ever seen! That the trigger was crisp and has the shortest reset of any striker fired pistol that he’s tried out. Needless to say, that got my attention! He then handed the pistol over to me so I could get feel for how it fit in my hand and dry fire it a couple of times. Palming this firearm was a real pleasure as it seemed to naturally fit my medium sized hand. Two pulls of the trigger with one reset in the middle of the dry fire sequence and it was true love.
Besides having a terrific trigger and a great ergonomic feel with natural point-ability, the pistol has ambidextrous controls for both the slide release and magazine release. The magazine release was the strangest item on this pistol to me with a release lever on both the left and right sides of the trigger guard instead of normal side button magazine release.
The factory installed three dot sights seemed very clear and I liked the fact that the rear sight is adjustable for windage. And for those of you who prefer .40 S&W, well you’re in luck because it’s offered in that caliber as well.
I handed the pistol back to the sales person with a sense of remorse that I just did not have the funds at that time to purchase it.
Note about the sights: the rear sight is adjustable for windage and elevation, and the front sight is adjustable for windage. JF
And from Popular Mechanics:
The Walther PPQ: 007's Favorite Handgun Gets an Update (http://www.popularmechanics.com/technology/military/weapons/the-walther-ppq-007s-favorite-handgun-gets-an-update-7865938)
I am feeling kind of 007 cool about my purchase! :cool:
Note: I don't know what the fella's problem was with the mag release, saying "You have to break your entire grip to get around to release the magazine and that is going to cost you time on your reload for sure." Others have said it is great because you can just hit it with your trigger finger without shifting your grip. I guess he needs to be schooled.

More posts from PPQ owners:
I bought mine about 3 months ago at Academy Sports for $525.00. I have put close to 500 rounds of various down range with no problems what so ever. It is very accurate. I mean very accurate. It is my daily conceal carry. I am Retired Military and have lobbed a few rounds down the range, this is a keeper.
This man's brother steered him strait!
I have to be honest, I was hesitant at first on getting a Walther. The only experience I had with a handgun was with the PPK .22, the James Bond gun that my father got from a friend of his at Los Alamos back in 68. He gave me the gun last year and I shot it couple of times. When I decided that I want a reliable handgun for self protection as well as home defense, I looked at Glock, Sig, S&W and HK. I settled on HK because it was ambidextrous and it was supposedly the best of the best. My brother, he carries the HK, suggested that I should look at the Walther because it's half the price of the HK, ambidextrous, and extremely reliable. The reason for my hesitation was the price. Granted, $500 price range is nothing to sneeze at, but at nearly half the price of my brother HK, I wondered how good and reliable it could be. My brother insisted that I do some research before I purchase the HK, and that if he had known about the Walther, specifically the PPQ before he bought his HK, he would have save some money and got the PPQ instead. After doing some research and saw nothing but positive review on the PPQ, I took a leap of faith and bought it. After putting couple hundred rounds through, I love everything about it. That is why I now want to get the PPS and to use that as the primary ccw when I'm out and use the PPQ at home.

When the slide returns to battery it has to strip a round from the magazine and chamber it. That slows the slide and absorbs some of the pounding.

actually I have never seen any semi workn out by battering. I am sure it has happened but I would tend to think more of a defect than anything like weak ass recoil springs. Again most people don't put enoughg rounds thrugh their guns to wear out even the first set of recoil springs.
recoil springs are low in price, replace as U SEE FIT...

I happened upon the Wolff Gunsprings website and they had 3 different recoil springs for the K9. I called their tech support and spoke with an older fellow about our issues with racking the slide. One of the 3 springs is a Reduced Power at 18 lb. He made it clear that the 18 pound spring was only for reloaders using light powder loads and would likely result in damage if used with "factory" ammunition. Not for us :-(

I don't buy that, but they are also CYA with that statement. Kahr use dto offer aPM9 ladys version and it had reduced power springs. I ain't gonna buy a 2# reduction in the recoil spring as a GUN BREAKER. Not in a million years.
Lets face it, ur gonna shoot 90% of ur rounds with over the counter fmj low priced ammo and the other 10% ur gonna shoot with +P ammo. Your K9 is not a pu$$y gun, it is built like a damn tank. WTf, we have seen on this fourm where some kahr techs have told an owner with hand racking issues in the cm9 series to just cut off a coil or two and it is alot easierto then insert the recoil assembly. Equate that into lost poundage!!!!
IMO. pure unadulterated bull sh!t.

Please, update this post when you can.
Things like Carpal Tunnel and Arthritis happen.
My bride is still able, but with difficulty, to rack the slide on the K-9. She is looking at hand surgery next week. A familiar and well traveled Colt Cobra is on stand-by.
Thanks,
