Well looks like a bought a lemon today. I just picked up a used Glock 43 that has no visible wear on it. When I got home and simply took the slide off to put oil on it I attempted to put it back together and this happened twice and now it seems that it's stuck this way. The spring basically fell out when removing the slide as well. Can anyone offer some advice and how to get it apart and what I'm supposed to do once I do. This thing appears to be a piece of garbage.
