I took my buddy with me to the range on Sunday. We shot my SR-22, my 9mm Sig P228, and my Browning BDA (Sig P220) in .45ACP.
He is 6'3, 225 lbs, and a former college hockey player, but he wasn't embarrassed at all to admit that his favorite of the three pistols was the little rimfire SR-22. He just had so much fun with it.
It's been a great piece for me--.22LR is super cheap to practice with, and the gun doesn't intimidate my two young sons at all (they flinch with the 9mm and won't even try the .45).
It is certainly not a match-grade competition pistol, but it is plenty accurate for recreational use and has been very reliable for me as well. I generally shoot Federal copper-plated.
