I hate to be the sour grape in the bunch,
but I had one of these and couldn't get rid of it fast enough. Its not that it wasn't accurate...it was, but it had several aspects to it that I could not live with.
It has a plastic "buffer" in the slide that needs to be replaced every 1-2k rounds, or the gun will batter the slide apart. There have been too many 22 pistols that don't have disposable parts for this one to pass muster.
My 22a was extremely unreliable even when spotless clean. It the only thing reliable about it was its habit of failing to eject every other shot. I had problems with the extractor, and overall showed poor fit and finish and a general lack of manufacturing quality.
I just plain hated the bloated grips.
If a person were to find a 22a for a good price (to me that would be under $150 LNIB) that had no feeding issues and a good supply of those dang plastic buffers already included with the gun, it would be a decent plinker.
This quote from the 22a users manual says it all to me though...
" Smith & Wesson has found wide variations in primer sensitivity between some brands of .22LR ammunition. Smith & Wesson recommends that before you put your .22LR handgun into regular use, that you fire several boxes of your brand of ammo through it to determine reliability of ignition. If failure to fire occurs, try different types or brands of ammo until a reliable loading is found."
So even S&W is saying they know they made an unreliable gun.
