I always try to clean my guns after each use, especially after learning that the residues left from shooting can cause corrosion. But, I always wonder if I made any mistakes putting it together. I'm not saying I'm not familiar enough with my firearms to field strip and reassemble them. I just wonder if maybe I missed/forgot something. Only one time have I had to re-reassemble something. That was a Ruger MK II and I got something on the wrong side of a pin so you couldn't pull the trigger. Anyway, my question is do you guys carry a freshly cleaned gun, or do you clean it every so many rounds, or every so many weeks, or what? I'm leaning toward every couple hundred rounds or every month or two whichever comes first, and not carrying it until it's been fired.
