357sig

How about a kahr in 357sig. Should be a real beast.
Any thoughts?:smash:

Isn't the .357 sig kinda .40 S&W? Would you maybe gain a carry round .357 over .40?

Although I have two guns that run 357 Sig and like the cartridge.
I doubt Kahr will produce a gun 357 Sig.
Not that it would be hard to do being a necked down 40.
Not all manufactures support this caliber.
And some that do seem to be phasing it out.
Although you can get some HK models in 357.
The new P30 only comes in 9mm and 40.

After shooting cases of 357 Sig I find they seem to be suceptable to bullet set back.
And have come across a higher percentage of out of spec LE ammo in 357 when compared to 9mm, 40 and 45.
In it's best loading the 40 comes close to 357 performance and has advantages in availability.

I'm happy with my Kahr MK40 Elite and wouldn't get a 357 barrel if available.
And I'm Barth Six Barrels.

Kahr should take a wise pass here. That is quickly becoming an even bigger orphan caliber than before.

I'd like to play with it, but then again, I'm one of those that likes odd calibers.

[mr surveyor]

nothing odd about .357 sig... just ask TX DPS;)

[Longitude Zero]

They and a few other agencies use it now but it has NOT gained the widspread acceptance that many folks in the industry thought it would. I know several agencies that once authorized it but have withdrawn support and de-authorized it. It has done even worse in the civilian market. In another 10 years I expect it will be a niche caliber only.

That's kind of where I was going with that, but again, you said it better than I do. Thanks.

I'm currently waiting to hear back about a custom .357sig barrel for my T40.
It's not a big deal to have one made, but what I wanted was polygonal rifling...that's the current holdup for me.

Don't think I would want to shoot one defensively indoors. Too loud. Bad enough at the range. OK outdoors with hearing protection.

[Gene Hackman]

Not a fan of 357 sig, I don't have any experience with it but it seems kind of like a novelty. And A lot of the times, when I shoot guns, it is to shoot until i'm completely satisfied with the reliability. It's a very expensive round. I believe some highway patrol units use 357 sig. They don't care what it costs. You're paying for it. How about a 10mm?

[Pointblank]

The 357 SIG will never go away completely because with many brands of firearms all you need to do is buy a barrel for your 40 to shoot it. I've done this with my Glock 27. Two things you will notice; you get a lot more muzzle blast, but a bit less recoil and it will wear your pistol out sooner. I woiuldn't do it in a Kahr.

Buy some underwood 40sw ammo and try it . 135gr at 1400fps + and my CC ammo 155gr at 13000fps + in a tp40 and more energy than a 125gr 357sig . There ammo tends to exceed advertised velocity .

I would rather have a 40super barrel for a 45 pistol if fast is really wanted . Just not in a light weight kahr .

Wow that 135 gr underwood 40 super load is a beast!

Muzzle Velocity: 1775 fps
Muzzle Energy: 945 ft. lbs.


As far as a 357 Sig in a kahr, I would not need one. YMMV

I have considered getting 9mm and 357 Sig conversion barrels for my XDM 40 S&W 4.5" many times. Sounds cool at first, but I always talk myself out of it. The 9mm I would only use for range shooting, never for self defense so not worth it to me. And the 357 Sig (after testing)I would probably trust to use for defense, but about the same ballistics can be had just running lighter .40 cal bullets in the factory barrel.

Figure its best to just stick to factory barrels and calibers in my auto's. If I want really big powerful boomers I just use my 357 mag and my 44 mag revolvers.

Compare Underwood .357sig to Underwood .40 and you'll see the .357sig still has the edge.
I got 1556fps and 671 lb-ft energy from my .357sig HK P2000 (3.66" barrel, which is shorter than the T40/TP40)
With the 135gr .40 Underwood load, it's 1400fps and 587 lb-ft energy from a 4" barrel.

Some people are really into statistics.........muzzle velocity, expansion, speed etc...........................if you have your magazine loaded with any kind of projectile, and you empty it, it should do the job. I surely wouldn't know whether I was shot with a bullet that expanded to 2"" and traveled at 1145 ft. per second, or whether it expanded to an 1 1/2 in. at a velocity of 5000 ft. per second. It hurts and kills regardless...........sometimes, numbers are everything...............in this case, not so much.:p

[JustinN]

Many years ago I had a .357 Sig in an XD. I was very underwhelmed and sold it off pretty quickly. I would have no interest in a Kahr in one....I'm trying to remember the last time I saw .357 sig ammo for sale somewhere. I know people still shoot it, I just don't see it.

oio Would you carry that lite bullet in the 357sig or a 124gr ?? Those light weight 9mm bullets don't penetrate as deeply as a heavier bullet that will still expand as well and travel deeper . Tried it with a supervel 1650fps 110gr 357 load on a deer back in the early '70's. Darn good thing I hit the heart as that's were the bullet stopped on a south florida 110lb deer . About 7" penetration .

Never liked light bullets for a given cartridge since . Tend to stay most times in a mid range weight driven hard .

The .357sig typically has options in 100gr to 147gr, and of course a few under and over those weights. Most typical is 124 or 125gr.
That's true; lightweight high velocity hp will not penetrate deep but the depth they DO penetrate will cause extensive damage.
There are specific bullets for specific needs, of course.
It all depends on what you're shooting at, that's why, regardless of caliber I think it's a good idea to have a mix in your magazine.
A hot .357sig FMJ load will penetrate far deeper than a .40 (with currently available bullets) in soft barriers like gel/tissue/etc. I personally measured about 34" from a Underwood 125gr fmj and about 31" from a S&B 140gr. There may be some .40 fmj that could duplicate those numbers (Fiocchi 170gr TC is an excellent one) , but I'm not aware of many others...probably some 180gr or 200gr from Underwood or Buffalo Bore.
There may not be a big enough advantage to justify .357sig over .40, but I've seen it, and I like bottleneck cartridges since they've proven to be more reliable than straight case. It's my preference, but it doesn't mean I'm right and others who prefer .40 are wrong.
Obviously the .357sig kicks a little less than comparable .40, so that in my opinion is also another advantage to staying on target.
I used to be a big proponent of 10mm, and wished HK and Kahr had offerings in that caliber, but, it's not really necessary considering other options.
Shot placement is the most important thing. Some people shoot better with a revolver or a .22....whatever works for them.
Although I do wish Kahr made models in .357sig, I'm in no way complaining about my MK40, K40, or T40...especially when you can get ammo mentioned above from Underwood, Buffalo Bore, and Fiocchi.

I am with you there.....very LOUD. Noise not worth the gain in my opinion. Ammo also hard to find and more expensive.

[hardluk1]

I know 357sig comes in147gr but its lost all its glory at that weight , Nothing special . I also have no use for custom barrels. My tp40 does all I want out of a lite weight pistol. and have no interest to push beyound the underwood loads . But a underwood engineer did say the 135gr load has least felt recoil over the heavier loads . Might have to try a box . I can say the 40sw brass from my kahr goes thru a RX die better than any other 40 brass I have found . Tight chamber, good timing to the handgun . far better than glock and m&p even with factory lite loads .

If I want to push the limits of common sense again , and I don't . I would drag out one of my DW revolvers and some Kevlar gloves ! I made some purely stupid loads for it when I was young . Glad I still have that revolver and all my fingers .

jeepster09 TYPE LOUDER . I can't hear your post . I hate indoor ranges . Ear plugs and good muffs are a must . I was at a outdoor range last week wearing good electronic muffs when some guy cut loose with a 338rum with an added muzzle break . Glad I did not have a firearm in my hands , might have dropped it grabbing for my muffs to see if they were on right . Felt like someone slapped you at 20 feet . Ever one moved back from the line to let him shoot till done .
