To magna port or to sell?

[midmo]

I have a CW40 that I am considering to sell or trade to get a cw9. I would like to keep it if I could get the recoil tamed. I see magna porting is $145. So is it worth it? Does it really tame the cw40?

[Bawanna]

I magna ported my K40, it knocked the edge off but it still has considerable muzzle flip. It looks good, they do a great job but personally I don't think it's enough.
I know others here love the 40 and I do also but prefer mid to full size 40's. You CW may benefit more from magna porting, I hate to steer ya towards a wrong choice.

My K40 mostly lives in the safe, I went to a PM45. To me it's not so much recoil but muzzle flip.

I'm sure others will be along with multiple directions and opinions and that's good for you. Digest them, make a pro and con list and move forward. Maybe keep the CW40, get the 9 and see how it shakes out.

Just save your barrel & buy this one from kahr's custom shop... http://www.kahr.com/Guide-Rods-and-Barrels/Kahr-40-Ported-Barrel-P40-and-CW40-PTBRL40P.asp

I have a Mag-na-ported P40 that I bought as is, but I don't really shoot it as well as my ported Glock 23C. I have a cobbled up set of sights... front is XS Big Dot and rear is Two-Dot Trijicon... not matched, but OK for close shooting. I was trying to approximate the HD Night Sights by Trijicon.

There is another choice... a Kahr ported barrel:

I bought one for my P9 and it seems not quite as effective as the Mag-na-porting, but it gives me a bit more barrel length and shoots well.

The flash is thrown forward and up, so it's not as bright as the Mag-na-ported ones.

My P40 "blog" is kind of long, but lots of freeze frames of the flash from Mag-na-porting with various kinds of ammo:

Porting an autoloader is less effective for felt recoil, compared to a ported revolver. Helps lots with flip though.

[midmo]

My main concern is the amount of flip.

[midmo]

What is the update that they are talking about?

[muggsy]

Sell the forty, buy a nine and don't look back. Cheaper to feed, easier to handle and just as deadly.

[Bills1873]

40 is a great round, but there's a reason 9mm is so popular. It's even more effective because one can shoot it better.

[berettabone]

People like me, who shoot .40 cal on a regular basis will tell you hogwash, as far as being more difficult to shoot than 9mm. Some people have real difficulty with recoil, others not so much. That "flip" helps me get the firearm back on plane for another shot. If you ever get a chance, shoot .40 out of an H&K. You'll know what I'm talking about.

[Bills1873]

I agree, Barettabone, and I regularly shoot 45 with much joy. But some people just don't like trying to manage much recoil. I like a bit of pop, and can shoot 45s all day. Started with the caliber many years ago, so just stayed with it rather than switch to 40.

[TheTman]

I bought the ported barrel, was a bit disappointed that it didn't do more. It helps muzzle flip SOME. Hard to say if it was worth the money. I suppose so.
As was said before, shooting them out of a heavier framed gun is a lot easier. The CW40 is pretty light weight. Thus harder to keep from flipping. I just go with the flip and bring back down on target. Not the greatest gun for double taps, but it can be done.

[Bawanna]

This is what I referred to. The HK is a much larger platform with more for the hand to control.

The recoil isn't really the issue in my case, just the muzzle flip. Magna Port is designed to address exactly that issue.

Just doesn't do it quite enough to work for me. I love my K40 but for a carry gun I can do without the muzzle flip.

[DougGuy]

The WHOLE POINT of a small, easily concealable, lightweight carry gun , is to carry as much caliber as you can. OF COURSE there will be more recoil and muzzle flip, there is not as much mass to absorb it as a full size gun. I never heard so much crying in my life! Just carry the thing, shoot it enough to be accurate and confident with it, and hope you NEVER have to draw and fire in a real life situation!

^^^^What he said^^^^....My first Kahr was a CW40 and I had it Mag-na-Ported which looked cool but in reality didn't do much to tame it....Went to a PM40 and didn't like shooting it more than a few times because of the recoil and the fact that you could kill small animals with the ejected brass, that thing didn't just eject brass, it fired um outa there....Currently shoot a PM9 and lovin it....Ammo is cheaper and recoil is mild....Save your money and forget the Mag-na-Port job and get a 9mm with some good SD ammo and be happy....

HK .40's aren't a fair comparison. I don't like the .40 in any other brand because my USP .40 spoiled me!

[berettabone]

My point being, I wouldn't shoot .40 out of any small platform. Notice, I own an MK9................If you don't like the "flip", you may either have to quit shooting .40, or get a larger platform to shoot it from. Some people just don't like .40 cal, they prefer .45 because of the flip with .40. I like them both.

I've heard that some guys by big guns to make up for small pee shooters. :)

[erichard]

The magna porting will make the gun significantly louder for the shooter just so you are aware. I'd go the 9mm route for more rounds in the mag and faster follow up shots. If you want a 40, the best gun I've tried with respect to recoil and muzzle flip is my HK USP. That gun will outperform any magna ported semi auto in .40, in my opinion.

Take a look at what a Lehigh XD 9mm round by Underwood in +P will do in gel. I think it's like a 2" wide wound track that penetrates over 16". Significantly better than .40 caliber hollow points.

Except some people want their cake and eat it too. I'd much rather have a gun that is pleasant to shoot than one that wears me down. Because I like to plink- a lot! Carrying a gun you aren't comfortable with because of recoil or whatever isn't a good idea.

That's why you carry a .380???????????:)
