Ive had my G27 for about a month now, I've ran about 700 rounds through it so far with zero problems with its operation. There are a few little quirks though that I was hoping you guys could help me with. First, when I fill my mags with 9 rounds, none of them seem to want to fit properly. When I do finally get the mags in all the way and hear the "click"...the mag release is so hard to push, it sometime takes both thumbs to push it and release the mag. After shooting my gun at the range and emptying the first mag, the rest of them go in so smooth it can almost be achieved by gravity alone. Second quirk, and I hope I explain this properly. The end of the spring on my RSA, the end that points to the exit of the barrel...seems to be working its way out and around the end of the black plastic piece. Has anyone seen this problem? Third and final issue I guess would be, the brass build up that has started on the feed ramp. I clean my gun regularly (after every range day) with Ballistol, I hear this is the best stuff to dissolve soft metals. I'm still unable to stop the build-up...any ideas?
