Nope, its a combat pistol. Ready to go out of the box. Its not a 1911 or Revolver that have a high number of internal parts and are delicate to different situations and break ins. Glocks do not have this problem. No break in required, although some guys on here might have their own break in but its mental not a requirement for the action of the gun.
