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

For shooters who put rounds downrange by the case, the trigger is the one part that can make or break a match — or a fun afternoon at the range. The Apex Competition Trigger Kit for Ruger Mk IV and Mk IV 22/45 is built for exactly that: no fluff, just a clean, repeatable break that helps you shoot faster and more accurately without fighting a heavy, mushy factory trigger. At $160, this is a straight upgrade that pays for itself in consistency.

What you get in the box:

• Complete trigger mechanism with a reduced-weight sear and hammer components
• Adjustable over-travel stop (set per the included installation video)
• Steel magazine safety delete plate (lets the pistol fire without a mag inserted — competition use only)
• Safety plate that maintains factory safety values

Real performance numbers: After installation and proper adjustment, you’re looking at a trigger pull weight of approximately 3.0 lbs, an 80% reduction in over-travel, and about 25% less overall trigger travel. The break is crisp — no creep, no grit, just a clean wall and a predictable snap. That’s the difference between a good run and a great one.

Fitment: This kit is a direct drop-in for all Ruger Mk IV and Mk IV 22/45 models. No filing, no fitting, no gunsmithing required. If you can field-strip your Mk IV, you can install this kit in under 30 minutes. The adjustable over-travel stop is set with a simple hex key, and Apex’s online installation video walks you through every step. The steel magazine safety delete is a simple swap — remove the factory plastic part, drop in the steel plate, and you’re done. No more fussing with a mag safety that can cause hiccups at the worst possible moment.

Who this is for: This kit is designed for competition shooters, range rats, and anyone who wants a no-nonsense trigger upgrade for their Ruger Mk IV. It’s not for defensive carry or LE duty — the adjustable over-travel stop and reduced pull weight are optimized for a controlled environment where every tenth of a second counts. If you shoot steel challenge, bullseye, or just want a better trigger for plinking, this is the kit. If you need a trigger for a carry gun, look elsewhere.

What you don’t get: No gimmicks, no fancy packaging, no overpriced “tactical” branding.
