Muzzle flip with a service pistol is the result of an improper shooting technique because typical service pistol cartridges do not generate enough recoil to generate muzzle flip when a proper grip is applied. Muzzle flip occurs when the pistol is held with the hand low on the grip frame. Next time you are at the range, fire a couple of rounds with your hand low on the grip frame, then try a couple more rounds with your grip adjusted so the web of your hand is tight against the tang, and you will find the latter provides much more control, allowing faster target acquisition, and faster aimed repeat shots.
