still have not got to try it...put together an Advantage Arms .22 conversion kit upper and mags on a Lone Wolf Distributing TimberWolf frame. Ran about 300 rounds through it of 36gr Federal. Maybe 10 hiccups of the fail to eject nature. Those were in the first 100 rounds. Will strip it down and run it through the untrasonic cleaner this week then Frog Lube it up. Also will do same to Glock 26. You know, for a gun that feels like crap in my hand, I can shoot the hell out if it. Groups were much better than same ammo through G17. Perplexing
