I have a Taurus PT92 and was thinking of getting a .22 for range practice and the reduced ammo costs. Just wanted to get some thoughts on getting something in .22 cal similar in design to the PT92. Is that a good idea? I'm not familiar with all the possibilities but poking around I've seen the Sig Sauer Mosquito & the Chiappa 1911-22. Any thoughts on these and what else should I look at?
