I'm very happy with this compensator - TRYBE Defense Universal Single Port 9mm Compensator

I admit, I was skeptical about this compensator but figured I'd give it a go for the price....I was wrong to be worried. Mounted on my Glock 48 9mm it reduced muzzle flip MUCH more efficiently than I would have guessed. The TIN coating (gold) has, so fat, held up to about 300 rounds in less than an hour. I'm extremely impressed so far. I highly suggest MORE thread lock though, the factory thread lock was not enough snd eas continuously backing out while shooting, nothing a little Loc-tite won't fix.
