My wife & I went shooting with another couple today. Holy smokes.....this guy has some cool stuff. He's got the desireable HK's, several fully-auto rifles, a number of suppressors, multiple class III sears, and 2 decked out Barrett's...one of which is the .50BMG with recoiling barrel. He brought along his FN5.7, because I had mentioned that I'd like to shoot one. It was a ***** cat to shoot, very nice. He had a threaded barrel on it, but didn't bring the can. He did bring his Glock 21 with a can, it shot much better with the suppressor. The recoil was very smooth and gentle, I am starting to think that I need to get an extra barrel for one of my pistols so I can have one too. I really liked the way it shot. I am very surprised at how the suppressor completely changed the feel of the gun. I did not expect it.
