Beretta 92 series compensator - Beretta 92 Series Muzzle Brake

I was a little hesitant at first in getting one of this, but after installing it on one of my 92XI'S and trying it out at the range I was blown away by the very noticeable improvement in getting back on target, I shot it to 10 yards at a pace of 2 rounds per second within a very respectable 3 to 4'' group.
I have them installed now on two 92XI'S one 92 Type X and one 92 FS.
Highly recommended.
Just as a side note, I tried it with a non OEM barrel made by a silencer company and there is about a 3/8'' gap between the front of the slide and the back of the compensator which looks a bit off but works just as well, this is due to the barrel been longer (Nothing to do with the product itself)
