I know it's not what you were asking at all, but I have the ruger lite sr22 and the beretta neos and an old iver Johnson trailsman. I honestly like them all equally for different reasons. the iver Johnson is small but heavy, but can fit in a pocket if needed. the neo's is a fine pistol, but incredibly long and a little akward, the sr22 is built extremely well and very accurate, but is picky with ammo. I usually suggest the beretta neo for new 22 shooter because of the price point. academy has them for under 250 no matter what barrel length you choose and it feeds whatever so far.
I, like most others, don't understand the motivation to buy a copy of a duty gun to shoot .22s, a gun should be built around the cartridge it's shooting, not just to look like something it's not. a .22 pistol should be an accurate target or hunting gun.
