Just my .22 cents worth but

1)
S&W 422 with a 4" barrel, light, accurate, fun to shoot and the mag release is in the middle for us lefties !
2)
This one comes with a qualifier...Taurus Tracker 6.5", blued in .22lr. MINE was super accurate, never jammed or had any problems, ever. Basically a poor mans Colt Diamondback. But from what I've read on here I got lucky with mine, as it had zero problems & a good double action trigger pull with no ejection problems. Big & heavy for a pistol, alot easier to carry than .22 rifle.
I would be leery about getting another one from what I've read on here. Would definetly want to test drive one first.
3)
OLD charter arms pathfinder .22 with the 1.5-2 inch barrel...fixed sights, misfires occasionally but man is the little bugger accurate !
The accuracy is the only reason I still have it.
Also have/had single sixes, MkII's etc. But they are well represented on here. That little 422 is hard to beat.
