I took this gun to the range and has some issues with the trigger bar slipping off. The first round went off and on the second, I could feel the trigger bar slip. What's strange is that it would fire a second, third etc... only after I released the mag just a little and then reinsert each time. I took it home and tried 3 different sear springs and now they won't even stay on the 2 dimples long enough for me to put the grips on. I ordered more sear springs so hopefully that works. If not, I guess I'll have to send it in to someone.
