My teen girls are ready to start some pistol training. I'd like to start them on .22 to get them used to handling a pistol before moving up to and EDC 9mm. Ideally I would like to have the transition be ergonomically identical. I'm looking at the Shield and .22 Compact, but they don't look ergonomically identical. Same with the Walther PPS and P22 (and I heard the P22 was picky with ammo). Then I thought about the G43 and a .22 conversion. Any suggestions?
