LOL all i can aford to practice with is .22. I shoot way more .22 than anything when i am the range i usaly put 50 or 100 rounds through my CCW and put it up and shoot about 500 rounds through my NEOS or my old .22 rifle. But to you orginal question do i practice with a .22 version of my cary gun sadly not. But if i had or they made a .22Makarov or Tokarev you bet i would.
I cant spell
