I've been wanting a .22lr revolver but haven't been able to track down an SP101 in that caliber. When an opportunity to trade for an older S&W model 63 came along, I took it. It may have been a mistake. The thing shoots reasonably well, but the DA trigger pull is garbage: heavy and raspy. I took the gun apart and cleaned it thoroughly. That helped a bit but not too much. I did, however, get a sense of accomplishment from figuring out how to put the hand back in correctly (after several failed attempts). I'm not sure if this gun is a keeper, but I'll give it some time. And perhaps suffering through its abysmal trigger will help me love my other guns more.
