VOLQUARTSEN | RUGER MARK IV PRECISION UPGRADES
The Stainless Look. The Volquartsen Competition Feel.
Give your Ruger MK IV a complete trigger-and-bolt upgrade with the Volquartsen Pistol Competition Kit featuring the Stainless Target Trigger. A crisp, clean 2.25 lb trigger pull, precision fire-control components, and Volquartsen's premium extractor and firing pin come together in one Made-in-USA kit built for serious rimfire shooting.
Some upgrades are worth doing together. Volquartsen pairs its MK IV Accurizing Kit with the Bolt Tune-Up Kit so the trigger system and the bolt's most important working components receive the same competition-minded attention. The stainless-finish Target Trigger gives this version a clean, classic appearance, backed by the precise machining and refined feel that have made Volquartsen a favorite among serious Ruger rimfire shooters.
A Crisp 2.25 lb Break, Finished in Stainless.
At the heart of this package is Volquartsen's Stainless Target Trigger, paired with a precision Target Hammer, Target Sear, CNC-machined disconnector, and supporting Accurizing Kit components. The hammer and sear are wire EDM-cut from A2 tool steel, bringing the manufacturing detail Volquartsen is known for to every trigger press.
The Target Trigger includes pretravel and overtravel adjustments to refine its feel. The result is a purposeful competition upgrade: a light, controlled break for shooters who appreciate precise feedback at the bench, during practice, and on the steel range.
Complete the Upgrade with a Bolt Tune-Up.
The Competition Kit goes beyond the trigger. Volquartsen includes its Exact Edge Extractor and SureStrike Firing Pin to give your MK IV a coordinated upgrade to case extraction and rimfire ignition. That combination makes the kit especially attractive for high-round-count shooters who want more than a trigger replacement.
The Ruger MK IV aftermarket includes respected names such as Tactical Solutions and TANDEMKROSS. When it comes to a complete trigger-and-bolt package, Volquartsen brings its own well-established reputation for premium rimfire internals, carefully selected to work together.
The Right Volquartsen Kit for Your MK IV
Like the classic look of a dark trigger? Choose the Volquartsen Competition Kit with Black Target Trigger. Prefer a brighter accent? See the Volquartsen Competition Kit with Gold Target Trigger. All three Target Trigger versions offer the same Volquartsen 2.25 lb trigger-pull design; the finish lets you make the pistol your own.
For a trigger-focused upgrade without the bolt components, explore the Volquartsen MK IV Accurizing Kit. The Volquartsen Bolt Tune-Up Kit is also available separately. For additional Ruger MK IV upgrades, consider the Volquartsen Competition Bolt and, on compatible 22/45 models, the Volquartsen Extended Bolt Release.

Frequently Asked Questions
Stainless trigger configuration, competition-kit contents, MK IV fitment, and authorized-dealer support.
What comes in the Volquartsen MK IV Pistol Competition Kit?
You get the complete MK IV Accurizing Kit with Stainless Target Trigger and the Bolt Tune-Up Kit, including the Exact Edge Extractor and SureStrike Firing Pin. It's Volquartsen's premium trigger and bolt upgrades together in one package.
Is this the stainless Target Trigger or the flat trigger?
This is the Stainless Target Trigger version, designed for a crisp 2.25 lb pull. Volquartsen's separate 19.22 Flat Trigger versions are designed for a 1.75 lb pull. This kit is the choice for shooters who want the classic Target Trigger feel with a stainless appearance.
How is this different from the black or gold Competition Kit?
The core upgrade is the same: Volquartsen's Target Trigger-based Accurizing Kit and Bolt Tune-Up Kit. The stainless, black and gold versions give you three ways to finish your MK IV while enjoying the same 2.25 lb Target Trigger design. Choose the look that suits your pistol.
Does this fit a Ruger MK IV 22/45 or 22/45 Lite?
Yes. Volquartsen designed the kit for factory-frame Ruger MK IV pistols, including the MK IV 22/45 and 22/45 Lite. It's the MK IV-specific competition upgrade, not an older MK II or MK III trigger kit.
Why choose the Competition Kit over just the Accurizing Kit?
The Competition Kit adds Volquartsen's Exact Edge Extractor and SureStrike Firing Pin to the full trigger upgrade. If you're updating both trigger control and bolt components, buying the combined kit is the straightforward way to get the complete Volquartsen package.
Does this kit change the magazine disconnect?
Yes. Installing the Accurizing Kit eliminates the factory magazine disconnect, so the pistol can fire with its magazine removed. Follow Volquartsen's instructions and confirm the pistol's safety functions after installation.
Is Pete's Pillars an authorized Volquartsen dealer?
Yes. Pete's Pillars is an authorized Volquartsen dealer. We carry genuine competition kits and carefully selected Ruger MK IV upgrades so you can shop with confidence and build around proven Volquartsen components.
