I don't agree. The recoil and feel in your hands are totally different, and you need to practice with what you are going to use. I'm normally pretty good with my 9mm M&P, but not after shooting a .22 for awhile. Takes a few mags to get back into the rhythm. If you're just practicing sight alignment, fine, but the rest is just not comparable and won't improve your shooting when it counts. Better to "waste" the money on the centerfire ammo.
