I shoot much more frequently because I have my .22 (CZ75 Kadet) than if I only shot my 9mm (CZSP01 Phantom), mainly due to the expense. I do all my dry firing practice, however, with the 9mm, so I can still keep that fresh in my memory, and anyway I get enough live ammo practice with the .22. As a result, I am improving with both, shooting more, and spending less.
