I've heard from a few people that there are certain things you shouldn't do with a 1911, and I would like clarification. If the slide is locked back, can you damage/effect anything by sling-shotting the slide forward by just pressing the slide release down with your thumb, with no magazine or rounds in the weapon? I was told this by my girlfriends father who builds custom 1911s for competition shooters. He said there is something about doing it that way that can dull the precision lockup of the gun. I may be completely explaining this wrong, because I trust what he says over what I know about them, because I am more familiar with my glocks, and they aren't really meant to be precision match grade firearms anyways. Also, I've heard that the sear spring can be damaged if you hold the hammer down, pull the trigger, and then ease the hammer forward with your thumb. The reasoning behind this was that the whole mechanism is designed to work in a specific sequence, and by easing the hammer forward with your thumb, you are making it go out of order. Thanks in advance for your help!
