Competition Trigger Kit for Ruger Mk IV and Mk IV 22/45

Description

For shooters who spend serious time on the range or in competition, the trigger is the single most important control on your pistol. The Apex Competition Trigger Kit for Ruger Mk IV and Mk IV 22/45 is built to deliver a precise, repeatable break that cuts through the distractions of a long, gritty factory pull. At $160, this is a focused upgrade for accuracy-minded owners who want their rimfire pistol to perform closer to a custom race gun.

This kit directly addresses the three biggest complaints about the stock Mk IV trigger: excessive pull weight, spongy overtravel, and a long reset. Once installed following the included video instructions, you get a clean, crisp break at approximately 3.0 pounds. That is a significant drop from the factory weight, which allows you to hold the sight picture steadier through the shot. The adjustable overtravel stop reduces excess trigger movement by roughly 80%, meaning the trigger stops hard right after the sear releases. There is no mushy wall to fight through. Overall trigger travel is reduced by about 25%, which speeds up follow-up shots without sacrificing control.

We specifically recommend this kit for competition and range use only. The lighter pull and minimal overtravel make it ideal for Steel Challenge, bullseye, or practice sessions where precision matters more than holster safety margins. Because of the adjustable overtravel stop, we do not recommend this for defensive carry or LE duty applications. This is a dedicated performance part for the firing line, not for a carry piece.

The kit includes two important components that keep your pistol safe and reliable. First, a safety plate maintains the factory safety values, so your Mk IV still functions as designed with the manual safety engaged. Second, a steel magazine safety delete is included. When installed, it allows the pistol to fire without a magazine inserted. This is a common modification for competition use, where a dropped magazine mid-stage should not stop you from finishing. The steel construction resists corrosion better than the factory plastic part, which matters if you shoot near the coast or in humid Florida conditions.

Fitment is straightforward for the Ruger Mk IV and Mk IV 22/45 models. The kit replaces the factory trigger assembly and does not require permanent modification to your frame. If you have a Mk III or earlier model, this will not work — it is specific to the Mk IV platform. The installation video from Apex walks you through each step, including how to adjust the overtravel screw for your personal preference.
