Need some help please, I haven't owned my Glock 23 very long and I'm not that proficient yet at tearing it down and putting it back together. I had attempted to install the LaserMax LMS1131 guide rod laser but discovered I needed a bushing. Well I thought I had it reassembled correctly however the slide won't pull all the way back. I've taking it back apart several times checking that the spring and slide lock were properly installed but I can't tell if it is or isn't. Any advice on how to correct this problem. There should be no reason for it to be jamming like that ad all I did was remove the spring and slide lock. Appreciate everyones advice and the knowledge on this Foroum.
