My first S&W, a model 22A, is reliable with all ammo, great trigger and balance in my hand. From a sand bag rest I can manage a two inch group, but they are seven inches high at 25 yards. That makes it mighty hard to hit the pesky Armadillos we are plagued with in these parts. Yes, the rear sight is all the way down. I am sure someone may have had the same problem and a suggestion short of sending it back to the factory would be appreciated.
