I was discussing my new XDM with a friend of mine who is a die hard glock guy. I told him that I haven't had a chance to shoot it, but I've cleaned it, and dry fired it, thats about it. His reply, "Oh, be careful, you don't wanna clean it too much. When I bought mine they said only clean it if you shoot it a bunch, but not if you only put a few rounds through it." Does this make sense to anyone? I know my father-in-law cleans all his guns once per year(maybe more), whether he shoots them or not, and everytime he shoots them he cleans them. I can't see how cleaning a gun could be bad for it. Clean it, oil it, put it away.
