VOLQUARTSEN | RUGER MARK IV COMPETITION UPGRADES
The Mark IV Upgrade You Feel on Every Shot.
A better trigger changes the way a pistol shoots. A carefully upgraded bolt makes the whole package more satisfying. The Volquartsen Pistol Competition Kit for Ruger MK IV combines a crisp 2.25 lb gold Target Trigger system with Volquartsen’s precision extractor and firing pin upgrades—a complete performance package for serious .22 LR target and competition shooters.
Volquartsen has built its reputation by refining the details that matter in a precision rimfire pistol. Rather than swapping only a trigger shoe, the Pistol Competition Kit brings together the company’s full MK IV Accurizing Kit and Bolt Tune-Up Kit. The result is a comprehensive upgrade for shooters who want a cleaner break, refined trigger control, and dependable extraction and ignition hardware in one purchase.
A Crisp 2.25 lb Target Trigger. Finished in Gold.
The centerpiece is Volquartsen’s gold Target Trigger, working with a precision target hammer, target sear, CNC-machined disconnector, and matching internal components. Volquartsen designed this combination to deliver a crisp, clean 2.25 lb trigger pull—exactly the kind of controlled, predictable break that makes time on the range and the firing line more rewarding.
Adjustable pretravel and overtravel let the trigger’s movement be set to the shooter’s preference. The hammer and sear are precision wire-EDM-cut from A2 tool steel, bringing Volquartsen’s careful machining to the parts behind the trigger as well as the gold trigger you see and feel.
More Than a Trigger Kit: The Bolt Gets the Volquartsen Treatment.
This is where the Competition Kit separates itself from a trigger-only upgrade. It also includes the Volquartsen Bolt Tune-Up Kit, pairing the Exact Edge Extractor with the SureStrike Firing Pin. These components are designed to tackle two of the most frustrating rimfire-pistol interruptions: poor extraction and inconsistent ignition. That makes the kit a compelling choice for high-round-count target shooting, steel challenges, and regular range use.
Ruger MK IV owners can choose from well-known aftermarket manufacturers such as Tactical Solutions and TANDEMKROSS when personalizing a pistol. But if your goal is to upgrade the trigger and core bolt components together, Volquartsen makes the decision straightforward: one complete kit, engineered as a Volquartsen system.
Choose the Volquartsen Upgrade That Matches Your Build
Prefer to concentrate on trigger feel first? Our Volquartsen MK IV Accurizing Kit with Gold Target Trigger gives you that premium fire-control upgrade on its own. Already happy with your trigger? The Volquartsen Bolt Tune-Up Kit is available separately with the Exact Edge Extractor and SureStrike Firing Pin. The Competition Kit on this page combines both—an especially appealing route when you are planning a complete MK IV refresh.
For shooters taking their MK IV even further, the Volquartsen Competition Bolt offers another premium level of bolt refinement. If you own a MK IV 22/45 and want easier access to the bolt control, consider the Volquartsen Extended Bolt Release for MK IV 22/45.

Frequently Asked Questions
What's included, trigger feel, Mark IV fitment, and buying genuine Volquartsen parts.
What comes in the Volquartsen Pistol Competition Kit?
You get the complete MK IV Accurizing Kit—including the gold Target Trigger, target hammer and sear, machined disconnector, hammer bushing, and associated trigger components—plus the Bolt Tune-Up Kit with Volquartsen’s Exact Edge Extractor and SureStrike Firing Pin. It’s Volquartsen’s trigger and bolt upgrades together in one package.
How is this different from the Volquartsen Accurizing Kit?
The Pistol Competition Kit includes everything in the Accurizing Kit plus the Bolt Tune-Up Kit. If you want only the trigger-system upgrade, the Volquartsen Gold Target Trigger Accurizing Kit is the focused choice. If you want the fuller trigger-and-bolt package, choose this Competition Kit.
Is this the gold flat trigger or the gold Target Trigger?
This version has Volquartsen’s gold Target Trigger, designed for a crisp, clean 2.25 lb pull. The manufacturer also offers separate 19.22 Flat Trigger versions designed around a lighter 1.75 lb pull. If you want the gold Target Trigger, you’re on the right page.
Will it fit my Ruger MK IV 22/45 or 22/45 Lite?
Yes. Volquartsen designed the complete Pistol Competition Kit for Ruger MK IV pistols, including the MK IV 22/45 and 22/45 Lite. This is the MK IV kit, not a complete fire-control kit for earlier MK II or MK III pistols.
Does the kit include the Exact Edge Extractor and SureStrike Firing Pin?
Yes—both are included in the Bolt Tune-Up portion of the kit. The Exact Edge Extractor is built for positive extraction, while the SureStrike Firing Pin is engineered for consistent rimfire ignition. There’s no need to buy the Bolt Tune-Up Kit separately when purchasing this Competition Kit.
Does the kit change the factory magazine disconnect?
Yes. Installing the included Volquartsen Accurizing Kit removes the factory magazine disconnect, so the pistol can fire with the magazine removed. This is an important change to understand when handling the firearm. Follow Volquartsen’s instructions and verify proper safety function after installation.
Is Pete's Pillars an authorized Volquartsen dealer?
Yes. Pete's Pillars is an authorized Volquartsen dealer, carrying genuine Volquartsen trigger kits, bolt parts, and premium Ruger Mark Series upgrades. We believe in Volquartsen’s approach to precision rimfire performance and are proud to offer its products to our customers.
