Volquartsen Firearms SureStrike Firing Pin for MKI, MKII, and MKIII Review

The Real Deal Behind the Volquartsen Firearms SureStrike Firing Pin for MKI, MKII, and MKIII

For years, I’ve been wrestling with a persistent annoyance: inconsistent ignition on my trusty Ruger Mark series pistols, specifically my MKI, MKII, and MKIII variants. This issue, characterized by frustrating “light strikes” that refuse to cycle the action or even ignite the primer, is a familiar foe to many owners of these otherwise excellent .22 LR semi-automatics. It’s especially galling when you’re in the middle of a good range session or, worse, when reliability is paramount. After trying various cleaning routines and different ammunition types with marginal success, I finally turned to a specialized upgrade. The Volquartsen Firearms SureStrike Firing Pin for MKI, MKII, and MKIII promised a definitive solution, and for a mere $26.00, it seemed like a worthwhile gamble.

My search for a remedy wasn’t born out of a desire for match-grade precision, but rather for uncompromised functional reliability. The factory firing pins on these older Rugers, while serviceable for many, can develop wear or slight variations that lead to insufficient impact energy. This is particularly true when combined with certain ammunition primers. I considered simply sourcing a new factory firing pin, but the allure of a component engineered specifically to eliminate light strikes, rather than just replace a worn part, was strong. Volquartsen Firearms has a stellar reputation for producing high-quality, performance-enhancing parts for Ruger rimfires, so the decision to try their SureStrike firing pin felt like a logical step.

Upon arrival, the Volquartsen Firearms SureStrike Firing Pin for MKI, MKII, and MKIII presented itself as a no-nonsense upgrade. It possesses a heft and finish that immediately convey its robust construction. The precision EDM machining and the surface-ground impact section are palpable even before installation. It’s a small part, easily overlooked, but it speaks volumes about the manufacturer’s attention to detail. My initial impression was one of quiet confidence; this wasn’t just a piece of metal, but a carefully crafted component designed to address a specific functional flaw.

I briefly glanced at some generic aftermarket firing pins, but their often-unspecified materials and manufacturing processes gave me pause. The SureStrike, with its stated use of A2 tool steel and specific hardening process, felt like a far more considered option. The promise of deeper hardening compared to conventional case hardening was particularly interesting. The immediate feeling was one of relief that a specialized solution existed, coupled with a healthy dose of curiosity to see if it truly lived up to its claims.

Real-World Testing: Putting Volquartsen Firearms SureStrike Firing Pin for MKI, MKII, and MKIII to the Test

First Use Experience

My initial testing took place in my workshop, which has become my de facto lab for firearm modifications and diagnostics. The installation of the SureStrike firing pin was straightforward, requiring only basic tools and a little patience for disassembling the Ruger bolt. It’s a simple drop-in part, designed to integrate seamlessly with the existing firing pin channel. The immediate difference was evident in the feel of the bolt assembly; the slightly wider diameter of the SureStrike pin contributed to a more snug fit within the bolt, reducing any perceptible side-to-side play that might have been present with the factory pin.

I then took my thoroughly cleaned and reassembled Ruger MKIII to my local indoor range. The objective was simple: to put it through its paces with a variety of ammunition, focusing on primers that have historically given me trouble. I loaded up with several different brands of .22 LR, including some known for harder primers. From the very first shot, I noticed a distinct improvement in the crispness of the hammer fall. There was a decisive “thwack” that had been missing before.

The ease of use was exceptional. There was no learning curve whatsoever; the part is designed to function identically to the factory component, only better. The only surprise, a pleasant one, was the immediate reduction in perceived bolt bounce. This might be a secondary effect of the more consistent ignition and potentially a slightly more robust firing pin spring interaction, but it was noticeable.

Extended Use & Reliability

After several range sessions and hundreds of rounds across my MKI, MKII, and MKIII pistols, the Volquartsen Firearms SureStrike Firing Pin for MKI, MKII, and MKIII has proven its mettle. The light strike issue has been entirely eradicated, regardless of the ammunition brand or primer hardness I’ve fed these firearms. This has transformed the shooting experience, allowing me to focus on accuracy and trigger control rather than worrying about cycling failures.

Durability has been superb. The A2 tool steel and its deep hardening to an Rc 56-58 rating are clearly effective. I have observed absolutely no signs of excessive wear or deformation on the SureStrike firing pins, even after consistent use. This is a marked improvement over factory pins, which I’ve seen develop peening or slight bending over time. Maintenance remains as simple as the original; the bolt disassembles easily for cleaning, and the firing pin requires no special attention beyond standard firearm care.

Compared to the factory firing pins, the SureStrike is a revelation. While budget options might offer a temporary fix, the material science and engineering behind this Volquartsen component clearly contribute to its long-term reliability and performance. It has consistently outperformed my expectations, solidifying its place as an essential upgrade for any serious owner of these Ruger rimfire pistols.

Specifications

The Volquartsen Firearms SureStrike Firing Pin for MKI, MKII, and MKIII is a critical component designed with meticulous attention to detail. It is precision EDM machined from A2 tool steel, a material chosen for its excellent hardness, toughness, and wear resistance. The impact section is then surface ground to ensure a consistent and optimal shape for reliable primer ignition.

This firing pin is manufactured to be .004″ wider than the factory firing pin. This subtle increase in width is crucial for minimizing side-to-side movement within the factory bolt, contributing to a more stable and consistent firing pin strike. The steel is hardened to a Rc 56-58 rating, a level that provides exceptional resistance to wear and deformation, significantly outlasting standard case-hardened parts. The USA origin of this part also speaks to quality manufacturing standards.

The A2 material allows for a deeper hardening process compared to conventional case hardening methods. This means the entire body of the firing pin is hardened throughout, not just the surface layer, providing superior longevity and resistance to breakage or excessive wear. Its Silver color is typical of treated tool steel and serves no functional purpose other than indicating its material and finish.

Performance & Functionality

The primary job of the SureStrike firing pin is to deliver a consistent and sufficiently forceful impact to the primer of a cartridge, ensuring reliable ignition. In this, it excels beyond measure. The consistent, sharp strike it provides has completely eliminated the light hits that plagued my Ruger Mark series pistols. This means no more failed ignition, no more limp-wristed cycling failures, and a significantly more enjoyable shooting experience.

Its main strength lies in its unwavering reliability. It simply does its job, every single time, with any ammunition I’ve tried. The slight increase in width and the precision machining contribute to a cleaner lockup within the bolt, enhancing overall functional consistency.
