Hey guys, Its been a while since I posted, but I just bought an RIA 1911 GI model. I LOVE this gun. To keep it short and sweet, When I lock the slide back (on an empty chamber with no magazine), hold just the grip safety, and then release the slide lock sending it home, the hammer falls to half cock, SOMETIMES.. Is this a big issue?

From what I read and hear, sounds like it could be a sear spring problem? This doesn't happen when I depress the grip safety, so that's what is interesting to this "noob" 1911 guy. I see a lot of posts and people say its OK to dry fire the weapon, I GUESS that still means I shouldn't be locking the slide, then releasing it on an empty chamber? Anything will help, thanks guys!!
