Mag-na-porting a Kahr CW45

Just some observations.
Many people have been intimidated by the recoil of a 45acp round in a light weight package like Kahr's CW45. And owning one personally, they are not without merit. It is a snappy little handful. Recently I had my gun magnaported to try to tone it down. After trying to research online the subject, there is just not that much information available. What I did find tho was enough positive to move forward. After getting the gun back and going to the range I have to say the change is dramatic. After over 100 rounds I can verify that both muzzle flip and felt recoil were both significantly decreased. All told, well worth the expense.
 
I have a Glock 23 and 23C, there is a noticeable reduction in muzzle flip with the C model.
I also have Lone Wolf extended ported barrel for the regular 23, again a noticeable reduction in muzzle flip.
 
What type of ammo are you using in your CW45?

Does Magnaport need the entire gun or just the barrel and slide?

Thanks,

Paul
 
The pistols with compensators or other types of porting I've tried seemed to be about as aggravating from the blast as the recoil had previously been.
Did you have a problem with that?
 
Lots of experience with Mag-Na-Port

I've had exactly the same experience with my four Mag-Na-Ported pistols. Nothing but positives with four different pistols.

The first was a S&W 438 and the decrease in muzzle rise was very substantial. I've also done a Sig P220 10mm, Glock 20 and a S&W 4 inch 627.

The 627 is my most recent, I had that one quad ported. I cannot get the muzzle to rise with full power loads using 158 gr bullet and 2400. Recoil goes straight back. Very, very impressed.

Usually you get a lot of misinformation from people that confusing porting with compensators. No, no increase in noise. No "night blindness", pretty much a huge fireball coming from a .357 magnum ports or not. I actually did my .357 magnum tests after the sun went down. Huge fireball forward with no ports, huge fireball at 45 degree angle with ports.

When I owned my G20, I used to switch between .40 S&W and 10mm using a conversion barrel, which took away the ports. The .40 had equal to or greater recoil than my 10mm reloads.

You'll have to play with your loads, though. The more powder the better they work. My Mag-Na-Ported .357 has much more muzzle rise with light target loads than full power magnum loads.
 
Firing a ported pistol from the “retention position” is something you’ll do just once.
In a close-quarters fight, you might not have the opportunity or desire to extend your arm and get your gun away from your body. Your eyes are likely to be in line with the blast from the ports. Very, very bad news for your eyes,
 
I was shooting 230 grain hardball. The service from mag na port , cost $145 plus shipping. Turn around time was less than 10 days
 
The ports are a "V" configuration. I have not found the noise to be an issue. I have a zastava cz999 in 40s&w with factory centerline porting. I have shot both in low light and no light conditions and have not had any problems with loosing my night vision. For me, it was well worth the extra cost. But it has to be a personal choice.
 
I just sent in my barrel and slide. Doing that allows you to use US postal. A cheaper option as you need to include the return postage cost with the parts. MAG NA PORTS website has all the details.
 
Michael T: Have you fired at night yet ?

God forbid that a ported gun be fired at night or near wispy clothing!

I really get tired of this old wive's tale being bandied about. One is no more likely to be visually affected by a ported barrel than the typical muzzle blast of most guns. If this is such an issue... How did revolver shooters fire a gun at night for more than a hundred years? Have you ever seen how much flame comes out between the cylinder and forcing cone?

I'm Blind, and my arm hair is on fire!
 
The only downside to porting that I know of is the (possibly blinding) blast from firing with the gun against your side down near belt level.
I have a ported Witness .45 that will strip the plating off thinly-plated bullets and spit the sharp little daggers back in my face. FMJs and JHPs don’t cause a problem. I haven’t heard of this problem with any other gun. Just my luck.

With the right load, any revolver will produce an amazing amount of flash.

The more powder the better they work !

YES ! I finally gave up trying to explain this to sporting clays shooters when porting became all the rage !! Porting really did nothing with typical target loads for a 12 gage !

earlier powders had neither the flash nor the blast supressors we have today.
 
Unnecessary ? The powder will all burn before it gets to the end as shotgun barrels are so long.. However with full loads you will still see a reduction in muzzle rise and recoil though not very great.

.
We did these tests with a very good and experienced shotgun shooter and a bunch of experienced clay shooters.
 
This continues the controversy, I think. Many shooters experience an improvement, and I think roughly as many do not. I Magna-Ported by K40 and noticed nothing at all, except an improvement in cool factor. Anyway, I'm certainly happy you had a positive experience--I'd definitely couldn't recommend it and wouldn't do it again.

I've not ever seen any experiments done (real experiments) to settle this, but it doesn't matter--data would never settle it anyway.

Have you ever seen how much flame comes out between the cylinder and forcing cone?

That is one of the finest discharging handgun photos I've ever seen.

I think night shots should always be done with AA No 5 or Longshot loads, to improve the drama.
