tHE PERFECT PISTOL SHOT
Locked arms are common in shooting. They are also detrimental to accuracy. Locked joints restrict blood flow and cause muscular movement. It is an unusual shooter that locks the arms and doesn't over-grip the handgun. Test it this way: Hold a sewing needle or pin at eye level, like a pistol sight. Focus on the pin and try to reduce its movement. Try with a locked arm and then with a naturally straight arm. We don't need muscle beyond what is required to hold a 40 ounce handgun in place in-between shots. Relax, you'll also last longer on the range.
Recoil management and a stable marksmanship platform begin with posture. No handgun made is capable of moving a human being through force of recoil, except in cases of shooter imbalance. When the feet are at a natural distance apart, and the weight is tending toward the balls of the feet, and the shoulders are forward of the hips, recoil will be limited to muzzle rise, which itself, is greatly diminished by the weight of the shoulder carriage (when forward of the hips). Over-grip and locked arms do NOTHING for recoil, and destroy accuracy.
Check your stance.
