So, I got a chance to thoroughly test mine today. I would say that overall, it performed pretty much the same as my two BC 25's, my BC 10, and two factory 10's. I do notice, though, that the feed ramp part of the mag lips seems to be bubbling a bit from heat after a full mag rapid fire. Not feeding quite as well after that - but I suppose easy enough to fix. Looks 200% better (at least) as well.
So, when can we get replacement feed lips?
BTW: no pics, but I have a SR-22 with an aftermarket release - TacSol style (mag with shell will not work with factory release - unless you trim the shell a bit), VQ auto release, bolt buffer, and some other goodies. My bro-in-law is visiting, and when we were packing up guns for the range, he said "I'm not really interested in taking the .22, but whatever you want".
As soon as he watched me drain a clip, he had to try - and then try some more!
