Hello. Name's Danny I just recently purchased my first firearm a glock 19 gen 3. I was initially going to purchase a gen 4 but they are not allowed in CA without having to jump through some hoops. I decided to purchase my first gun after an attempted break in at my home while we were out on vacation. Thank god for my security system. Looking to learn a lot from you guys. 1st question. I notice every time I clear my gun.(remove mag, check chamber, aim in safe direction, pull trigger) and then disassemble the slide I see that the spring has come up from its spot and I have to push it back down to where it should be. is that common? I have never fired this weapon.
