I no longer have my 22A, but it was plenty accurate and seemed to function well even with target ammunition. I had a Millett 3MOA dot sight on it; the target in the picture is 50 rounds of Aguila Golden Eagle Match Rifle off the bench at 25 yards. I also tried Aguila Golden Eagle Match Pistol & Target, Federal AutoMatch, Remington Target and Winchester T22 Target. The Federal, Winchester and Remington gave me more fliers than the Aguila but it all shot pretty good. As with every other .22, it takes some trial and error to find out what they like.
After I had it for a couple of months, it started to slam-fire. Doubles at first, but a few triples as well (with several makes of ammunition). Not needing that sort of excitement, I sent it back to S&W on their nickel and it worked fine after that.
S&W will also send you a couple of recoil buffers for free if you ask for them. They seem to compress in use to a certain point and then no further; I ran the same one in mine for a couple of thousand rounds. I'd say if the little cutout in the buffer for the guide rod gets worn to the point that it won't stay securely in place it might be time for another one. Changing them more often sure won't hurt anything; I just don't feel like it is necessary. The first time I field stripped the pistol the guide rod and buffer launched into space; I found the rod, but never did find the buffer. Fortunately, they had included an extra in the box.
I found that the 22A needed more lubrication than was indicated in the owner's manual. When wear patterns started to be noticed, I would apply a tiny amount of Gun Butter in those areas and functioning was greatly improved.
The trigger on mine did have a little grinding creep just before it broke. I swapped it (and a good bit of cash) for a Model 41 and, well, there is no comparison with the trigger on the 41 but the price range of each gun is far different so each is what it is.
In their class, they are pretty good little guns.
