They do not use the luxury of taking their time to make sure everything is "just so" when shooting. Their grip on the gun is muscle memory. The extended grip safety helps to place the web of the hand correctly.
For those who grab the grip "high" have figured that the felt recoil is reduced, but that offers a small piece of the web of the hand to the hammer or slide.
You are just referring to the grip safety itself and not the modification of the frame when it comes to competitive shooting, right? No matter the application, competitive, recreational or carry, the idea is to get the uncomfortable/unsightly metal out of the way of snagging the web between the index finger and thumb?
