I've been spending the winter months going through my gunsafe & cleaning my many neglected firearms. I live in the desert so rust is nver a problem but some of them were getting a little dirty in the action from repeated firing. I carried a Sig P226 for 18 years as a LEO & loved the gun. It was simple to disassemble & hardly ever had a misfire. I also carried a P228 off duty & on special out of uniform details. It too was flawless! I cleaned my Ruger 22/45 yesterday & could not get the thing back together properly. I got so frustrated I left it last night & after a little research figured out what I had done wrong. I hadn't put the trigger in the right position while reassembling it & the mainspring got jammed. I've took it apart a couple more times just to be sure I had it down. I had a similar problem a few weeks ago putting my 1911 Kimber back together. The point is; Sigs are so damned simple I guess I got a bit complacent with the 22/45 & the 1911. Lesson learned: READ THE INSTRUCTIONS! At least most of my guns are now clean!
