VOLQUARTSEN | RUGER MARK IV PRECISION UPGRADES
Love Your Trigger? Upgrade Everything Behind It.
Already have a Ruger MK IV trigger you like? Keep it. The Volquartsen Pistol Competition Kit — No Trigger pairs the precision fire-control internals of Volquartsen's MK IV Accurizing Kit with its Exact Edge Extractor and SureStrike Firing Pin. It's the serious Made-in-USA competition upgrade for shooters who want Volquartsen performance without paying for another trigger shoe.
The best pistol builds are personal. You might prefer the feel of your existing MK IV trigger, or already have a favorite shoe installed. Volquartsen gives you a way to build around that choice. This no-trigger Competition Kit delivers the Target Hammer, Target Sear, CNC-machined disconnector and supporting Accurizing Kit components, together with its dedicated Bolt Tune-Up Kit. You choose the trigger face; Volquartsen supplies the precision components doing the work behind it.
Volquartsen Fire-Control Precision. Your Choice of Trigger.
Volquartsen's Target Hammer and Target Sear are wire EDM-cut from A2 tool steel, while the disconnector is CNC-machined. That precision manufacturing is the foundation of the clean, controlled trigger feel Volquartsen is known for among rimfire target and competition shooters.
Rather than making you purchase another trigger shoe, this configuration lets you retain an appropriate trigger style you already enjoy. Shooters comparing Volquartsen, Tactical Solutions and TANDEMKROSS MK IV upgrades will recognize the advantage: a Volquartsen competition-grade internal system with freedom over the trigger face. Trigger-shoe compatibility and final adjustments should match the components in your specific MK IV.
The Bolt Gets the Full Tune-Up, Too.
This is more than a no-trigger Accurizing Kit. The included Volquartsen Bolt Tune-Up Kit brings together the Exact Edge Extractor and SureStrike Firing Pin for positive extraction and consistent rimfire ignition. For regular target practice, steel competition or a favorite weekend MK IV, it's a compelling way to address the trigger internals and bolt components together.
That combined-package value is why the Pistol Competition Kit earns its place in the Volquartsen lineup: you get a coordinated precision upgrade rather than piecing together the fire-control and bolt components one item at a time.
Prefer a Complete Trigger? Choose Your Volquartsen Kit.
If you're starting fresh and want a Volquartsen trigger shoe included, we also stock the Competition Kit with Black Target Trigger, Stainless Target Trigger version and Gold Target Trigger version. Each pairs the MK IV trigger upgrade with the same Bolt Tune-Up concept. The No Trigger version is ideal when your trigger preference is already settled.
For a trigger-focused upgrade, explore the Volquartsen MK IV Accurizing Kit. For a bolt-focused refresh, the Volquartsen Bolt Tune-Up Kit is sold separately. You can take the build further with a Volquartsen Competition Bolt or, on compatible MK IV 22/45 pistols, a Volquartsen Extended Bolt Release.

Frequently Asked Questions
What you get, choosing your trigger, Ruger MK IV fitment, and genuine Volquartsen support.
What exactly is included in the No Trigger Competition Kit?
You get Volquartsen's MK IV Accurizing Kit internals—including the Target Hammer, Target Sear, CNC-machined disconnector and hammer bushing—plus its Bolt Tune-Up Kit with the Exact Edge Extractor and SureStrike Firing Pin. The only major difference from the complete trigger versions is that no trigger shoe is supplied.
Can I keep the trigger I already like?
That's the idea. If you already have a trigger style you enjoy, this kit lets you focus the upgrade on Volquartsen's premium internals and bolt parts without buying another trigger shoe. Make sure your chosen trigger is compatible with the MK IV fire-control components.
Will this give me a 2.25 lb trigger pull?
Volquartsen designs its Target Trigger-equipped Competition Kits around a crisp 2.25 lb pull. This version supplies the same precision-oriented internal upgrade but no trigger shoe, so the final pull and adjustment feel depend on the trigger you pair with it and your pistol's setup.
How is this different from the No Trigger Accurizing Kit?
The Pistol Competition Kit adds the full Exact Edge Extractor and SureStrike Firing Pin Bolt Tune-Up Kit to the no-trigger Accurizing Kit. It's the complete Volquartsen internals-and-bolt package for shooters who already have their preferred trigger.
Does it fit the Ruger MK IV 22/45 and 22/45 Lite?
Yes. Volquartsen lists factory-frame Ruger MK IV models, including the 22/45 and 22/45 Lite. The no-trigger version is still the full MK IV Competition Kit internal upgrade, just without an included trigger shoe.
Does it change the factory magazine disconnect?
Yes. The Accurizing Kit eliminates the factory magazine disconnect, meaning the pistol can fire with the magazine removed. It's an important operating change to understand, and Volquartsen provides installation instructions for the kit.
Is Pete's Pillars an authorized Volquartsen dealer?
Yes. Pete's Pillars is an authorized Volquartsen dealer. We offer genuine Volquartsen competition kits, bolt upgrades and Ruger MK IV components so you can build around the precision parts you want with confidence.
Small Change. Big Impact. Pete's Pillars.
