Ported barrel?

What is the benefit of having a ported barrel on a Glock? I have a Gen2 G23.

Reduced recoil. But at the cost of increased flash and spraying unburned powder over you. Many of us do not thing it is worth it.

I have an extended ported G27 Storm Lake in 357 Sig that I like a lot.
Haven't noticed any additional muzzle flash at the range.
Or been sprayed with anything.
Also have an extended ported barrel on my Sig P220 45.

IMHO - the porting seems to be much more effective with the
high pressure high velocity 357 Sig than the sub sonic .45 ACP.

Opinions very on porting a 40 S&W.
I don't have personal experience to share on that.

Does not reduce recoil, it reduces muzzle flip, so your followup shots can be quicker. Doesn't create excessive flash, burn your eyebrows, damage your chromosomes, etc. Causes lots of hate on internet forums, but otherwise does no harm whatsoever. I like porting.

Really thinking on getting a Storm Lakes ported barrel to reduce muzzle jump and if I dont like it I can always put the stock Glock barrel back in, it takes all of 30 seconds and for $125 a barrel is pretty cheap.

I really enjoy my ported Glocks, I have seen so many people with hate for these from Internet rumors and have never owned one, so they go from hear say and not experience. I have shot mine at night with no problem with flash. And powder blowing back??? I haven't even heard this rumor yet. Lmao from what I have found there is nothing negative about the C models. I just wish people would give a report on something they actually own!

In reality, there is no downside, no noticeable difference in flash, no problems firing at night or from retention, when using factory ported glocks and any commonly available ammunition. That said, the average shooter does not shoot at level where they would benefit from porting. Porting makes more rapid follow-up shots possible in the hands of a skilled shooter. It will not compensate for lack of proficiency, nor will it make a mediocre shooter shoot well. The benefit is less noticeable in 9mm than, say, .40S&W. Kodiak, Elijah, and Josh would be correct.

I have a ported Glock 22 and the only thing I noticed was that the front site got dirty quicker. Recoil was slightly less also. I like it.

I've got 40 + years of experience with muzzle-ported barrels that says you are wrong. You force me to conclude that, 'many of us' don't know your butts from your elbows when it comes to barrel porting AND how to use a ported barrel properly.

I used to swap in an extended/ported barrel into my G23 when I used it to shoot practical pistol matches. I used it for quicker follow-up shots, as I double tap all papers. It served it's purpose well and I have no complaints. And I can definitely attest that these issues do not exist: "increased flash and spraying unburned powder over you"

I had a 19C for the wife years ago. It was a real sweet shooter. I would say the only downside would be velocity lost for carry ammo. Anyone have numbers on ported/non-ported velocity differences?

I don't have any numbers. But I'd be willing to bet there is zero measurable difference in the ability of either to stop a threat. I can say pepper poppers fall the same either way.

I have no way to back this up, but after I bought my 17C I remember reading some data that indicated a loss of maybe 75-100 FPS. Not that much, considering the benefit. And my memory could be foggy on that...either way I remember thinking it was somewhat negligible.

The difference is negligible. If I were hand loading for competition, it might be factor, but not for standard loads.

Yes. The answer is that, 'It depends!'

Years ago the factory, in an off-moment of uncharacteristic candor, published the information that Glock's slide/barrel porting combination lost muzzle velocity in the range of between 3 and 4 percent. (A number which I've seen verified, before, on this board.)

ON THE OTHER HAND: The extended barrel and muzzle-porting setup that I use on all my Glocks loses nothing and, in fact, actually seems to pick up muzzle velocity.

My dual muzzled-ported barrels are custom-built to my own specifications and are extended 5/8's of an inch on my G-21's, and 6/8's of an inch on my G-19. These dual slit-ports might get you a 3 to 5 percent decrease in muzzle flip when you're firing slowly; but, when the rate-of-fire is constant, the decrease in flip can (at my best guess) increase to as much as 12 to 15 percent. (Some people have told me, '15 to 18 percent'; but I don't think so.)

Is a relatively small reduction, like this, in muzzle flip worth it? Some of the argumentative guys I shoot with - Who are not usually believers in ported barrels - have remarked after shooting one of my Glocks, (and I quote) 'That damned barrel actually works!'

It does!
