My almost yr old SR22 pistol didn't want to pull the spent casing out of the barrel at the range the other day. Had to strip off slide and pull out by hand(fingernail). Called Ruger and they are sending me out new extractor and spring for free(NICE). Went to u-tube found video of complete disassembly so it doesn't look to complicated. Just have to pick up a couple of pin punches of the right size. Anyone have any tips or tricks of what not to do other than what was in video?
