These are my only 2 revolvers. The top is a 22-4 and the bottom is a 629PC. I have had the 629 for about 3 months and just bought the 22-4 this weekend. The 44mag shoots great, and haven't had any problems out of it. The 22-4 for me was not shootable with the stock grips. I kept gripping the upper part of the trigger with my finger and the holes were all over the place. I put the Hogue grips on it for now so I can shoot again this week.
I really like the idea of the 45acp as I am a 1911 guy. To be honest these will probably be my only 2 revolvers.
