USPSA Handgun Competition Rules January 2008

5.1.4 Unless required by a Division (see Appendix D), there is no restriction
on the trigger pull weight of a handgun, 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 Handguns must be serviceable and safe. Range Officers may demand
examination of a competitor’s handgun or related 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or unsafe by a Range Officer, it must be withdrawn from the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.
5.1.7.3 The competitor’s replacement handgun and its appropriate
ammunition must be chronographed per Rule 5.6, regardless of
whether or not the original handgun was previously tested.
5.1.7.4 If the original handgun/ammunition was not previously tested,
and if the original handgun has already been used on a stage, and
can be safely fired (i.e. the malfunction is not related to an
inability to safely fire the handgun), then the original handgun
and its ammunition supply remain subject to testing.
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 more than one handgun during a
course of fire (see Rule 10.5.7).
5.1.10 Handguns with shoulder stocks and/or fore grips of any kind are prohibited.
5.1.11 Handguns offering “burst” and/or fully automatic operation are prohibited.
5.2 Holsters and Other Competitor Equipment
5.2.1 Carry and Storage – Except when within the boundaries of a safety
area, or when under the supervision and direct command of a Range
