I've been stripping my 1911 down and cleaning it thoroughly after each trip to the range even if I've only fired 50 or so rounds through it. Today I took it and the M1 out and this evening it hit that I only take the M1 down once a year because frequent takedown and reassembly can affect accuracy and the tightness of the fit and isn't recommended. I clean the bore, grease the metal to metal contact areas I can reach without disassembly, and wipe down all metal. While I wouldn't go that long between disassembly and serious cleaning of the 1911, is it really necessary to do it after firing less than 100 rounds? Can I go 200, 300, 500 rounhd spread over a few weeks? What do the rest of you do?
