+1 I HEAR they are a pain to take apart and put back together, but in the 5 years of owning my 22/45 I have never had to disassemble it, and it is one of the best 22's I've ever owned. I had a bunch of internal work done by a good ruger gunsmith here, and slapped a red dot on it and a couple other little toys and it'll shoot minute of golfball out to 50 yards+ all day long.
