Sidearms & Scatterguns Has anyone gotten tired of a long barrel in their Glock 21?

I'm contemplating a 6" barrel for some extra velocity, will I regret it?

depends on what you plan on doing with it i suppose.

A long barrel without a long slide is kind of silly. If you want more power just get a larger cartridge conversion or switch to 10mm.

Check out the Barrel By the Inch tests.

I don’t think the 1” deference makes much in terms of velocity.


It does soften the muzzle blast when shooting without ear pro

Here is the .45 acp where they chop the barrel

You gain 30-50 FPS with the extra inch

Back to the question- I have a g35 barrel in a G22.

I don’t notice the extra length

I think it just depends on how you intend to carry. For instance IWB would be miserable with extra barrel hanging down poking your ass/thigh. But OWB or chest carry you won't even notice. But typically when you get a Glock with an extended barrel it comes with the standard barrel? And or you end up with a standard barrel from swapping them. That said, you can get standard Glock barrels pretty cheap anymore so it wouldn't be a big deal to switch back. Or really you could probably find somebody who wants to swap.

my G21 with a TB is just as accurate if not more than my buddies G41 both are @ 5.31" but
the ticket is the trigger on mine is a Zev. probably the most accurate .45 I own. How much
velocity do you think you would gain by more than the normal extension?

I run a LW threaded barrel out of my G21. Since I only use the G21 as a nightstand and field gun, it's great. I've modded my holsters to accommodate.

I've noticed some pretty big FPS bumps from the extra .5", especially using Double Tap's 255 .45 SMC loads.

Running a threaded 6.6" barrel in my G20 (I know not G21). Had a 6.02" unthreaded barrel before. I like the extra weight up front for faster follow up shots, especially with a can.

No, because I would never buy a Glock.

I gave my 21 to my dad because I just liked the 41 so much better. I’ve not ever considered getting a longer barrel in it though. Just isn’t something I feel is necessary or beneficial ??‍
