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

Description

Drop this Apex Competition Trigger Kit into your Ruger Mk IV or Mk IV 22/45 and you get a crisp 3.0lb pull with 80% less overtravel. That’s the short version. The long version is a steel magazine safety delete, a safety plate that keeps factory drop safety specs, and a trigger that actually breaks like a competition gun should. This competition trigger kit for Ruger Mk IV and Mk IV 22/45 is built for shooters who want clean splits and zero creep at the range or in a match.

Key Features

• Reduced Trigger Pull to ~3.0 lbs — WHY IT MATTERS: Lighter pull means you stay on target through the break, not fighting a heavy trigger shoe. That’s the difference between a hit and a miss on a tight steel plate.
• Overtravel Reduction by ~80% — WHY IT MATTERS: Less overtravel means the trigger resets faster and your follow-up shots come quicker. You feel the reset, not the slop.
• Steel Magazine Safety Delete — WHY IT MATTERS: Lets you fire without a mag inserted, which is standard in USPSA and Steel Challenge. Keeps you running when a mag drops or a stage requires an empty chamber start.
• Safety Plate Included — WHY IT MATTERS: Maintains factory drop safety values so your gun stays safe even after the trigger job. No trade-off between performance and reliability.
• Drop-In Installation — WHY IT MATTERS: No fitting, no filing, no gunsmith. Follow Apex’s installation video and you’re done in under 30 minutes.

Who It’s For

This kit is for Ruger Mk IV owners who shoot competition — Steel Challenge, USPSA Rimfire, or any match where trigger speed matters. It’s also for plinkers who want a better trigger without buying a new gun. If you’ve got a Mark IV and you’re tired of the factory 4.5-5lb pull with all that creep, this is your fix.

Pros / Cons

• Pro: 3.0lb pull is consistent, crisp, and repeatable. No grit, no stacking.
• Pro: Magazine safety delete is steel, not polymer — won’t crack or wear out.
• Pro: Overtravel adjustability lets you dial it in for your shooting style.
• Con: The magazine safety delete is competition-only — if you carry or plink with mag safety laws, you’ll want to keep the factory part. Apex includes the safety plate, but you lose the magazine disconnect.

Comparison: Apex vs Timney vs Volquartsen

Feature	Apex Competition Trigger Kit	Timney Triggers Mk IV Kit	Volquartsen Mk IV Trigger Kit
Pull Weight	~3.0 lbs	2.5-3.0 lbs	2.5-3.5 lbs
Overtravel Reduction	~80%	Adjustable	Adjustable
Magazine Safety Delete	Steel (included)	Not included	Not included
Safety Plate	Included	Not included	Included
Installation	Drop-in, no fitting	Drop-in, no fitting	Drop-in, no fitting
Price	$160	$185	$175

Bottom line: Apex gives you the steel mag delete and safety plate at a lower price than Timney or Volquartsen. If you want the absolute lightest pull, Timney edges it out by half a pound. But for the money and included parts, Apex is the better value for competition shooters.

FAQ

Does this kit work with all Ruger Mk IV serial numbers?

Yes. The Apex Competition Trigger Kit is compatible with all Ruger Mk IV and Mk IV 22/45 pistols, regardless of serial number. There’s no serial number restriction — it fits every Mk IV variant Apex has tested.

How does this compare to the Ruger Mark IV competition model’s stock trigger?

The Ruger Mark IV Competition model has a factory trigger around 4.5-5 lbs with noticeable creep and overtravel. This Apex kit drops pull to ~3.0 lbs, reduces overtravel by 80%, and gives a crisp break. It’s a significant upgrade over any factory Mk IV trigger, including the competition model.

Is the magazine safety delete required for competition?

Not required, but highly recommended for USPSA and Steel Challenge. Many stages require an empty chamber start, and the mag safety delete lets you fire without a magazine inserted. If you don’t compete, you can leave the factory mag safety in place — the kit includes the safety plate either way.

Will this void my Ruger warranty?

Installing aftermarket parts doesn’t automatically void your Ruger warranty, but Ruger may deny claims if the part caused the issue. The Apex kit is drop-in and reversible, so you can swap back to factory parts if needed. Most shooters keep it installed with no problems.
