Everyone has pretty much said it. If not carrying, the RO with adjustable sights would be great. As for the guide rods, I prefer the standard GI guide rod in my carry guns, but fairly recently added a Wilson full length for extra weight up front and to avoid recoil spring kink. They got their money from me. I've never had a spring kink up, and the full length guide rod is just as easy to disassemble without tools as the standard. I feel no difference in reliability. Biggest recommendation: whichever you choose, buy quality mags.
