The Mercury Arms 45 is a semi-automatic pistol chambered in .45 AP. It is the most common firearm in human space with civilian and military personnel alike. It features a smart slide that shows how many rounds are left in the magazine.   The MA45 was widely used as far back as the Solar Wars. Replacements have been suggested by many younger officers, but veterans and the Old Guard insist on keeping it in service.
