This Competition Trigger Kit is a drop-in replacement for the Ruger Mk IV and Mk IV 22/45 that addresses the factory trigger’s long, gritty take-up and excessive overtravel. The kit delivers a crisp break at approximately 3.0 lbs, reduces overtravel by roughly 80%, and shortens total travel by about 25%. A steel magazine safety delete is included, allowing the pistol to fire without the magazine inserted—recommended for competition use only. The adjustable overtravel stop must be set per the installation video. This component is intended for competition or range use, not for LE duty or defensive carry.
