Read the original post... New to handguns ... get it? here's some more of the original post....But the NEED for a .22 is outmatched by the fact that the other calibers out there destroy it simply because they are more useful and practically applied in the real world whereas the .22 is not.Hence the reason training and .22's were suggested. It's rarely successful to start a NEW SHOOTER out on larger calibers... oh, wait... this has already been discussed, and logic explained.... but you obviously didn't get it then either. Best of luck to ya.Then I started thinking about ammo. From what I've read, it seems 9mm ammo is 4-5x the cost of .22lr. Given that I'd like to become proficient and not skimp on range time due to ammo costs, it seems I'd be well served by having the ability to shoot .22 ammo, especially early on in my shooting. And given that I want my range time with a .22 to carry over to my self defense pistol, it seems I should go with either a pistol that can be easily converted to shoot .22 (and easily converted back), or two pistols that are very similar, one chambered for 9mm, the other for .22.
