I'm going to be learning that during this coming weekend's guard drill. My unit armorer told me to bring my Colt with me and he'd go through and show me how to completely strip it down and re-assemble it.The only thing I would recommend is to learn to detail strip it. While you don't have to do more than field strip it to clean it. It is good to detail it every 2-3 k rounds.
Other than that, maybe Wilson or Novak mags for it.
I've only had the pistol for a couple weeks now and I already love it. I don't understand why the military got away from it. Its a great weapon.
