I clean my Mark III 22/45 after every range session even if I only burn 50 rounds through it. After you get the hang of it, you can do it as fast as any other gun. I can fly through mine now but I must admit, the first time, I sat for near an hour and a half wondering how the hell it went back together. Once ya get it down, it's smooth. When I bought it the guy at the store said it was near impossible. Now, after my 15 or 20th time, he's full of it. It's easy and if anyone ever needs help feel free to PM me.
