I saw a much more experienced shooter adjusting his grip after every shot. I don't understand, he was only shooting a CZ-75 SP-01. Why would you need/want to adjust your grip after every shot?
Well, he probably has a certain grip that works well for him that is conducive to accuracy and he has to readjust because his gun/ammo combination does not allow him to retain his grip under recoil. Hollywood made him buy the wrong ammo perhaps, LOL!
I know when i pitched in baseball, I had my "ritual" that i did before each pitch, that was just my deal though and it seemed to work. But as long as i have been shooting i have never heard of more experienced shooters adjusted their grip after each shot, unless they were changing the way they were shooting.
I'm doubting this was the case, but if my left hand fingernails get too long, after about 5 shots, they dig into my right hand, so I re-adjust. Now I've just cut them off but I imagine I will forget again.
Actually, back in the old days, I saw experienced bullseye shooters occasionally do this. Something about "readjusting each step for perfection" .
Time wasn't much of an issue in bullseye, but in today's fast-paced shooting world, not a good idea. Rapid recovery and consistent accuracy is enhanced
by fewer steps in the shooting process.
