What a difference! I have fully disassembled my XD40 a couple of times and had a heck of time with the mag release and the grip safety. I sat down with my SA Mil Spec the other night to do a full disassembly using the guide in the sticky. Much, much easier. Everything went back together so smooth. The simplicity of the design is so much nicer than messing with a bunch of tiny springs that need to fit in tight places. I think I appreciate the 1911 more each time I work with it.
