Itís always about safety.
Some of the fastest pistol shooters I know will "flinch" on a dummy round. It is not actually a true anticipation flinching, but it is a hard, fast trigger pull. As long as the flinch is slower than the lock time of the weapon, it is not really going to hurt accuracy.
Bullseye shooters will be rock solid and you will never even know they pulled the trigger on a dummy round. Unfortunately, speed causes compromises in perfect technique at times. On a pistol with no overtravel, I am rock solid. On a pistol with over travel, you would swear I flinch like crazy. Its not flinch, its just the fact that my trigger pull is very fast and very hard. When I shoot bullseye, totally different.
