The problem is the button is pressed in. The pressed in section is knurled and that is all that retains it. They could spot weld it when assembled and it would never come apart, or put the end through a washer and peen it over like a rivet. I think it's great that they replaced it so fast, but if they keep breaking, what good is that! I bought the gun for CCW, not one to bring to the range once in a while because you can't rely on it. My 6 glocks have never failed this way. I would never hesitate to carry one of those. It really sucks because otherwise this is a great pistol, small, accurate, easy to conceal, plus comfortable to shoot. This really disappoints me. I think they are really dropping the ball on not doing a redesign on such a small and probably very cheap part. They probably will lose more in replacing the stupid things than just fixing the problem. They redesigned the whole line with the model 2.0, yet did not fix this. Sorry for the rant, just really bothrers me seeing a good company making a poor decision. Especially since these are probably their best selling firearms.
