I shot a steel plate rimfire match today with my 22/45....I was accurate, but slow.....but that's not the problem....I got home and decided it was time to fieldstrip it and give it a good cleaning. I haven't done that since last year when I stripped it, put it back together - it would not fire and I could not take it apart again....well, you guessed it...the very same stinkin' thing happend this afternoon. So tomorrow morning, I'm carrying it back to the shop, to get them to take it apart and make it functional again. After it is again functional, I'm going to ask if he will watch me fieldstrip it and put it back together, and tell me what I'm doing wrong.....if not, I'll take it to another gun shop (that I like better anyways), and trade it for either a S&W 22A heavy barrel, or a Walther P22 5" barrel....I would prefer the Walther, but the Smith is a lot less expensive....I would hate to get rid of the Ruger, but I just can't deal with a gun that I cannot clean.......just wanted to get that off my chest.....
