Crap
This is a very bad layout the comp is mounted off the guide rod and I don’t mind that but it rests against the slide and frame so if shot it would mark both in a none repairable fashion very quickly. Also jiggles all over the place you can move it almost an 8th inch in all four directions, largest concern is if it self corrected at the 1/8 inch down blocks the top edge of the barrel and will contact the round as it comes out.Verified purchase: YesCondition: New

Worked a lot better than I thought it would. I prefer front heavy guns and this fills that gap on my G17.3 It actually made a huge difference in muzzle flip.Verified purchase: YesCondition: Pre-owned

AWESOME COMPENSATER
The Strike Industries Compensater for my Glock 17 Gen 3 arrived, nothing but AWESOME! I was like a kid who just received his detective decoder from JC Penny's. Cant wait to install, but with Christmas right around the corner I'm busy.Verified purchase: YesCondition: New

Not really a great value
While this does dampen muzzle rise it's very difficult to install with the recoil spring that's included. It also extends the slide to the point where none of my holsters will fit it.Verified purchase: YesCondition: New

No Complaints
Use it on select fire G17 at 1200 rpm. It keeps the pistol dead accurate without muzzle rise. Great product!
