That is porting — doesn’t the comp extend beyond the “regular barrel length.” So what are velocities with the comp, comparing for example, a regular Glock 19 and a 19 with a Mayhem?Originally Posted by NoTacTravis

True. With my post you quoted I was only attempting to address the drop in muzzle velocity coming from the porting that YVK mentioned.
For a porting vs. comp. direct comparison you can see this link: Although it is also imperfect in other ways.

Mainly the thrust of what I was chiming in on is the "do comps work for 9mm" part of the debate. From my reading it seems that they do indeed and that there are objective tests that seem to verify this. Whether or not people like them, wish to run them, or see them as useless for wimpy 9mm loads, in their more manly hands would seem to be a subjective matter.
Looks like factory porting brings +P loads down to somewhere between +P and regular. Maybe we'll call it +/- P.

It's a well established fact at this point that comps do make a difference. How much of a difference is a matter of comp design, gun used, ammo used, and the shooter.
"Is it worth it?" is probably only going to be answered on a case-by-case basis with each individual having to weigh the pros and cons in their own mind.
My own opinion is don't knock it till you try it, but I could also be guilty of invested bias.
As a human, here's my impression.
A G19 shooting Speer Lawman with a comp feels like a G19 shooting gamer ammo.
It's noticeably softer shooting and easier to get back on target sooner, but that's the order of magnitude of difference in feel.
Not earth shattering, but definitely noticeable. The timing of them is weird and feels "artificial" to me. It seems like there's more complex stuff going on in tracking the dot visually with the comp, but I haven't spent time to fully tune RSA and other parameters to maximize them.
I don't run a comp on my open gun, FWIW. I won't ever use one for a real carry gun (too loud and blasty).
The interesting thing about CCforlife is that he has said that he knows and quantifies the hit he takes in performance using a G26 over a G34. So it's not like he thinks the G26 shoots better for him overall, it's that he chooses to not use it.
I feel the same way about comps. But I carry a P365. Can't say that I ever felt an urge to buy the SAS ported version.
Okay, I kind of love this gun after shooting it today.
I had a new experiences rich day today, like shooting LTT RDO, trying on a T1 holster and, you guessed it, shooting a Roland, KKM barrel etc. I had some 115 gr Lawman so it was hot enough. I do wish I had my G19 with a WML for better comparison but all I had was a G26. Even then, I could see that the comp did work.
Weak interest in Mayhem for G26 grew into a modest interest.

There are times loud and blasty can be a good thing.

Someone linked to this on a 2011 forum but no reason you can't do it on a Glock.
Its called the Chunk Port, although there is some argument as to whether its a Comp or a bigass Port.
Hmmm... if you have a mill laying around you could DIY. I kid but maybe with some refinement this could be an viable option.
