Ported PM9

[rockem_sockem]

What is everyone's impression of a ported PM9? I'm looking to buy a used PM9 that is ported, but have never seen that done to a kahr. What are thoughts on pro/cons of the porting....
Thanks!

I can't believe I beat Jocko on this one.

I don't see any cons to porting. I did my K40. It looks cool, it helps tame the muzzle flip. Even in low light the flash is diverted so it doesn't effect our night vision. They say no reduction in velocity.
Your buying used so no warranty issue although I don't believe porting would effect warranty anyhow but don't know that for fact.

I'd not hesitate to purchase one that was ported. I'm a big magna port fan.

Awesome! That's good to hear! I haven't seen much porting on any guns I've looked at in the past couple years, so I just haven't seen/heard much about it lately. Thanks for the +1

Is there any argument to losing velocity in a ported barrel?

[Bawanna]

Magna Port says there is virtually no reduction. Some would argue that there has to be some loss. If there is it has to be very minimal. In a 5" or less barrel not worth losing sleep over.

[Bawanna]

APW Cogan says in their testing of ported GLOCK pistols, the average loss was 8%. There's some other interesting things to think about it...

They port a bit differently than Magna Port. They are ported more at an angle to the sides so the escaping pressure is diverted at an angle rather than straight up.
The Cogan would seem to work more efficiently in reducing muzzle flip but couldn't say how much.

Magna Port works, I do know that.

no sense in my chimming in, u guys did a nice job.. I was never a fan of drilling round holes on top of the slide and barrel.. .

Depends on your shooting style. If you use a traditional stance porting shouldn't be a problem. If you use a bladed stance with the gun held close to your chest porting is ruled out.

[jocko]

Why would a person shoot with the gun close to his chest in the first place. I would thinhk it would be awkward and very difficult to use the sights at all. Emergencies maybe but actually training in that postion just to me seem so awkward. For me this is the first time I have even heard ot this "bladed stance".

The biggest arguments against a ported gun for defensive/combat use are typically:

A) Flash Blindness

and

B) Powder Burns

Sure both of these things could happen, but IMHO:

A) Flash Blindness---depending on the ammo you use, it's not much of an issue, even in a short barrel gun, casue if your ammo causes that big a "flash" then you probably need to choose a different ammo, or change your loading if you hand load (yes, some people do choose to hand load their defensive ammo)

B) Powder Burns---most of this argument stems from the angle of should you be in a physical struggle with an assailaint when you pull the trigger, causing burns. If this is the case, there is just as likely (if not more so) a chance that if anyone is going to get burned it will be the assaliant and not you.

Again, it's possible both of these (as well as other issues) could happen using a ported gun for defensive purposes, but if you shoot it better then a non ported, and are comfortable carrying as such, go for it!

Usually the gun is still extended at arms length even with a bladed stance. The gun is still a little closer to your face since your arm is crossing your body rather than straight out in front but still far enough away that flash shouldn't be an issue.
As rotoflyer mentioned in a up close hands on struggle the flash could get either of you or both. Shooting from a jacket pocket will most likely burn your jacket some but small price to pay if the shot saves your neck.
The little lightweight revolvers have been ported at the factory for years and the same issues are present. Never heard of it being that big a deal. Guess it's all about trade offs.

Incidently I use a semi bladed stance, park at about a 45degree angle to the target generally rather than straight on. I do occasionally shoot straight on too just for drill but prefer a little angle if I can get it.

oh hell I have shot that way alot with all of my ported guns and that is a non issue,m trust me on that. Didn't know it had a name attached to it. Wonder what they would call my position of just sitting in a chair with crossed legs and resting over my legs??LAZY STANCE. probably..

No thats called the Bawanna stance or a modified bladed chair stance.

[jocko]

I shoot that way alot at the range when by myself,just more enjoyable for me. To old and to many aches and pains to try all this running stuff and hiding behind a barrel etc.

Question for anybody with Night Sights and porting. Does shooting dirty ammo get the front sight dirty and therefor dim, or harder to see? Even if you don't have night sights does the front sight seem to get dirty worse than normal?

Thanks
