Tim at SAS made this for me several years ago. I no longer own the Glock 22lr conversion or the Rem40X 22lr that I used it on so it's on the chopping block. Welded core comes out for easy cleaning. I'd approximate the round count at 300 through the can and I've cleaned it several times so it's in good shape. Be the only cool kid with a titanium 22lr suppressor on your block. $375 in Indy via FTF sale (all NFA rules apply of course) or $380 shipped to your FFL/SOT.
