There is absolutely merit to it, and luckily for you the arguably best 22lr pistol atm is cheap as shit. For most people training on a full size handgun is easiest, but as long as you don't get retarded and buy a tiny micro compact I have faith you will figure it out just because you're doing due diligence and asking here, which means you will probably bother to look up grips and training guides.
