5.1 Action Air Handguns

5.1.1 Action Air handguns are regulated by Divisions (see Appendix D), however, courses of fire must remain consistent for all Divisions.

5.1.2 Approved Action Air Handguns are those which fire plastic projectiles of 6mm diameter.

5.1.3 Sights – Types of sights identified by IPSC are:
5.1.3.1 "Open sights" are aiming devices fitted to a firearm which do not use electronic circuitry and/or lenses. Fiber-optic inserts are deemed not to be lenses.
5.1.3.2 "Optical/electronic sights" are aiming devices (including flashlights) fitted to a firearm which use electronic circuitry and/or lenses.
5.1.3.3 The Range Master is the final authority in respect of the classification of any sights used in an IPSC Action Air match and/or their compliance with these rules, including the Divisions in
Appendix D.

5.1.4 Unless required by a Division (see Appendices), there is no restriction on the trigger pull weight of a firearm, however, the trigger mechanism must, at all times, function safely.

5.1.5 Triggers and/or trigger shoes that extend beyond the width of the trigger guard are expressly prohibited.

5.1.6 Firearms must be serviceable and safe. Range Officers may demand examination of a competitor’s firearm or allied equipment, at any time, to check they are functioning safely. If any such item is declared unserviceable or unsafe by a Range Officer, it must be withdrawn from the match until the item is repaired to the satisfaction of the Range Master.

5.1.7 Competitors must use the same handgun and type of sights for all courses of fire in a match. However, in the event that a competitor’s original handgun and/or sights become unserviceable or unsafe during a match, the competitor must, before using a substitute handgun and/or sights, seek permission from the Range Master who may approve the substitution provided he is satisfied:
5.1.7.1 The substitute handgun satisfies the requirements of the relevant Division.
5.1.7.2 In using the substitute handgun the competitor will not gain a competitive advantage.

5.1.8 A competitor who substitutes or significantly modifies a handgun during a match without the prior approval of the Range Master will be subject to the provisions of Section 10.6.

5.1.9 A competitor must never use or wear on his person more than one firearm during a course of fire (see Rule 10.5.7).

5.1.10 Handguns with shoulder stocks and/or foregrips of any kind are prohibited (see Rule 10.5.15).

5.1.11 Handguns which "burst" fire (i.e. where more than one projectile is discharged on a single pull or activation of the trigger) more than once during the same COF will result in the competitor receiving a zero score for that COF.
