I don't think it's too effective on anything but that's me, some do. Big Grin


Sadly I own a magna ported gun that I wish wasn't. Sadly, some day I will own two.

I'm generally of the opinion that it's the shooter, not the gun. But there are some that can make use of the small advantage.

The only gun I have that's magna ported is an officer's 1911 in 45 ACP. The porting is effective, but only with full power loads.

I have no idea your exact question. But I run a number of competition guns with comps to help shot to shot times and you need a lot of gas for them to have any effect. Simply factory 9 it is not going to make much difference. What problem are you trying to solve.

Mag-Na-Porting worked great on my Desert Eagle .50. Not to reduce recoil per se, but to reduce twisting of the firearm as a result of its rotary action. Eliminated the brass to forehead problem.

Don't see much use for it on a 9x19mm.

Glock has some "C" models in 9mm. Is there a chance you could rent say a 17 or 17C and compare the differences? That might be the easiest way before you have work done on the HK.

Years ago when Mag-na-port was first introduced I was very interested in the modification and had it done to a couple of revolvers. The reviews and analyses at the time reported that the effect was most pronounced with the more powerful cartridges like 357 and 44 Magnum. I suspect the value in a 9mm pistol would be very limited.

I have a ported MP9 CORE. I like that gun but I hate the porting. Only thing it does in 9mm is make a more pronounced pressure wave. Better shooter than me may notice it being flatter shooting, I can't notice enough to care shooting it side by side with my unported MP9. I have considered buying a unported barrel to replace it I dislike it that much.

Issue I am trying to solve is reduced recoil for my tendernitis. Shooting my 226 or M11-A1 takes away a lot of the recoil.

I once ported an S&W Model 13 in an effort to help with controllability during double taps with full power .357 ammo.
And it worked.
But the giant V shaped muzzle flash was a big drawback. Lots of increased noise, too.
Flash less powder is now more prevalent and the 9mm may be less prone to flash and noise.
So, for me, porting is only for rifles and shotguns.

I have factory ported glock models, such as the 19c. I cant tell much difference between the 19 and 19c.

Porting reduces muzzle rize, but not really recoil.

In a .357 magnum or larger, magnaporting is nice. I have it on various fevolvers. It's well done and useful. It does make for a dirtier pistol to clean.

9x19 isnt really a high powered, stiff recoiling cartridge; you'll get more from the weight of the pistol than you will from magnaporting. You'll find that wider backstraps are more comfortable to shoot, and that some pistols are more comfortable than others.

I have a Glock 19C. It is noticeably louder than the noncompensated version. Also, it makes the front sight really dirty and isn't totally safe for shooting from a close retention hold due to the way it spits debris straight up in the air.
I usually shoot it with the nonported barrel in it.

Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with." -Douglas Adams

A G19C is the only unreliable Glock I've ever owned. Replacing the ported barrel with an unported one solved that problem.

I don't believe I've ever had a semi auto done, but in revolvers with 357 mag and above, I think it made a difference.

I shot one of the old Michigan Arms 1911s with Auto-Ports by Magnaport through slide and barrel. I could not tell a lot of difference. But that was years ago, my arthritis might appreciate it now.

Goo point with weight. Size (especially large slides) and weight are major factors in recoil reduction for me. My SIG's (226 & M11-A1) are my softest shooters even more so than my Beretta PX4 Storm with the rotating barrel.

If you have/buy a threaded barrel,

try a muzzle brake, one with ports on the side, which are designed to propel it forward,

ports on top will reduce rise.

That combination will be very close to the total cost of the Mag-na-porting after S&H.

aesthetically not as pleasing but not ruined if you don't notice a difference, develops undesirable characteristics.
