.22s are great for learning/practicing sight picture, sight alignment, and trigger control. Past that, they don't replicate most center-fire pistols very well. The conversion kits do a little better in getting used to the controls of the center-fire pistol. Recoil management pretty much requires a center-fire pistol to practice with.
I learned on 9mm and .45ACP pistols. It can certainly be done effectively. However, I also like the ability to practice on the cheap! Four cent .22 allows a lot more practicing of the fundamentals than forty cent .45 rounds. (That said, I tend to do both! )
