Although many say it doesn't,,,
I firmly believe that it does.
The only reason I can hit a 4" chest shot with my Model 36 snubbie in .38 Special,,,
Is because of the many hundreds of rounds of cheap .22 through my Model 34 snubbie in .22 LR.
Pretty much the same for my Bersa Thunder 380,,,
My Bersa Thunder 22 allowed me the cheap practice to become proficient.
The naysayers will say that the recoil difference will negate the practice,,,
I say they are simply incorrect in their summation.
Making a mountain out of a molehill,,,
So to speak.
Trigger time is Trigger time,,,
In the event anyone needs to use their centerfire,,,
I doubt very much whether the difference in recoil will factor in at all.
But if you think it might,,,
Shoot 5 magazines .22 and one of centerfire as a routine.
All I can "factually" say is,,,
It worked for me.
