There is no need to go out and purchase equipment to compete in a Tactical Police Competition. You already have the gear you need: a duty handgun, a patrol rifle and shotgun are all you need to be successful. Below are the rules pertaining to your equipment.
Be sure to review the full tactical police competition standards.
Firearms used in NRA Tactical Police Competitions must be duty type firearms. Firearms designed for competitive shooting, even those based on duty gun models, and firearms that have competitive accessories or modifications are not allowed.
Based on the features of the competitor's firearms, he will compete in either the Patrol or Tactical Division. While there are other restrictions, the basic difference between the Divisions is:
Patrol Division: All firearms used must have mechanical sights (iron). Shotgun must be pump action.
Tactical Division: Handgun and shotgun must have mechanical sights. Shotgun may be pump or semi-automatic action. Rifle may have one optical sight, such as a telescopic, red dot or holographic sight.
Invitational Division: At the discretion of the Tournament Director persons who do not meet TPC eligibility requirements may be allowed to participate. These may include volunteer match officials, match sponsors, and firearm industry representatives. Invitational competitors are not eligible for awards, plaques, or prizes. Recorded scores are maintained and published separately from regular competitors.
