Agreed…Repeat an exercise often enough, and it becomes relegated to muscle memory. Notice the use of the word "about". Clinching the pistol as tightly as one can with both hands doesn't, based on my own experience with handgun shooting, strike me as better for anything except fighting to maintain possession of one's firearm.That’s how I look at it...If I train thoroughly enough, often enough, that IS how my body will respond under pressure.
I think Hack said it best: “You’ll not rise to the occasion, but default to your level of training.”
Personally, I believe that it takes the average person a MINIMUM of 1,000 reps for something to become engrained into their muscle memory. This works both for us and against us. If it’s a solid technique, that’s good. But if it’s a training scar, that’s bad.
A good example this (in the form of a “training scar”) is the famous FBI shootout where the guys actually saved their spent brass from their revo’s because that’s what they did on the range.
