US12449231 - Laser induced friction surface on firearm

The patent describes a method for enhancing the coefficient of friction on the external surfaces of firearm components by applying a laser to fuse particulate friction material onto them. This process aims to increase the roughness of grips, frames, slides, or rails, thereby improving grip and control.

Claim 1

1. A method for increasing a coefficient of friction of an external surface of a grip, frame, slide, or rail of a firearm, the method comprising the steps of: disposing particulate friction material on the external surface of the grip, frame, slide, or rail of the firearm; disposing a laser machine adjacent to the grip, frame, slide, or rail so that a laser beam of the laser machine is in a line of sight to the external surface of the grip, frame, slide, or rail of the firearm; adjusting the laser machine so that laser beam is capable of fusing the particulate friction material to the external surface of the grip, frame, slide, or rail of the firearm to increase a roughness of the grip, frame, slide, or rail of the firearm; applying the laser beam of the laser machine onto the external surface of the grip, frame, slide, or rail of the firearm with the adjusted laser machine to fuse the particular friction material to the external surface of the grip, frame, slide, or rail of the firearm for increasing the coefficient of friction of the grip, frame, slide, or rail of the firearm. disposing particulate friction material on the external surface of the grip, frame, slide, or rail of the firearm; disposing a laser machine adjacent to the grip, frame, slide, or rail so that a laser beam of the laser machine is in a line of sight to the external surface of the grip, frame, slide, or rail of the firearm; adjusting the laser machine so that laser beam is capable of fusing the particulate friction material to the external surface of the grip, frame, slide, or rail of the firearm to increase a roughness of the grip, frame, slide, or rail of the firearm; applying the laser beam of the laser machine onto the external surface of the grip, frame, slide, or rail of the firearm with the adjusted laser machine to fuse the particular friction material to the external surface of the grip, frame, slide, or rail of the firearm for increasing the coefficient of friction of the grip, frame, slide, or rail of the firearm.
