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

Description

For serious competitors and shooters who demand precision from their Ruger Mk IV or Mk IV 22/45, this Competition Trigger Kit delivers a measurable upgrade where it counts: on the scoreboard. Designed for those who treat their rimfire pistol as a training tool or match-ready platform, this kit replaces mushy factory components with a system built for repeatable, consistent performance.

The core benefit is a crisp, predictable trigger break that eliminates the guesswork at the sear wall. When installed following the included video guide, the kit reduces pull weight to approximately 3.0 lbs—light enough for fast, accurate splits, but heavy enough to maintain control during high-speed strings. The adjustable over-travel stop cuts excess movement by roughly 80%, and total trigger travel is reduced by about 25%. This means less wasted motion, faster resets, and more time keeping the sights on target between shots.

Safety is not compromised for performance. The kit includes a factory-spec safety plate that preserves the pistol’s original safety values. For competition use, the included steel magazine safety delete allows the pistol to fire without the magazine inserted—a standard modification for stages requiring empty-chamber starts or quick reload drills. This part is specifically recommended for range and match use only.

Specs & Fitment:

• Compatible with Ruger Mk IV and Mk IV 22/45 models (all barrel lengths and versions).
• Trigger pull weight: approximately 3.0 lbs.
• Over-travel reduction: approximately 80% (adjustable).
• Total travel reduction: approximately 25%.
• Includes: Competition trigger, safety plate, steel magazine safety delete, and installation guide.
• Price: $160.

Important fitment note: This kit is designed for competition and range use only. The adjustable over-travel stop and reduced pull weight make it unsuitable for duty, defensive carry, or any application where a heavier, more deliberate trigger is required. For serious shooters running drills, Steel Challenge, or USPSA Rimfire, this is a direct path to faster, more accurate splits without sacrificing reliability or safety.
