Ive been thinking almost the same thing, to get similar .22LR & 9mm pistols. I was thinking developing my basic pistol marksmanship with the .22LR, before & in addition to, working with the 9mm would be cost effective. However, 9mm is cheap. Not as cheap as 22LR but pretty cheap. The cost of a decent .22LR pistol buys a whole lot of 9mm. I may get a .22LR pistol anyway, but it wont be because its a cost effective training strategy.
