Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV Review

The Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV: First Use to Final Thoughts

When it comes to firearms, especially semi-automatic pistols like the Ruger Mark IV series, even minor design tweaks can have a significant impact on the user experience. I recently found myself in a situation where a subtle but persistent issue with my Ruger MK IV was impacting my shooting sessions. Specifically, I noticed that during rapid fire, my thumb would occasionally, and inadvertently, nudge the safety lever into the “safe” position. This wasn’t a constant problem, but it was disruptive enough to warrant a solution. After some research, I discovered the Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV, a small but potentially impactful upgrade designed to address exactly this kind of user-specific challenge.

My search for a solution led me to this particular spring. While there are always generic spring kits available for firearm modifications, Volquartsen has a reputation for precision engineering in the rimfire world, making their offering particularly appealing. My initial impression upon receiving the small, almost unassuming package was one of minimalist efficacy. The spring itself is a compact piece of polished metal, fitting the description of a specialized component rather than a generalized one.

I had briefly considered just trying to adjust the original safety mechanism or perhaps looking for a slightly different grip panel, but these felt like less direct solutions to the problem of the safety lever’s inherent sensitivity. The Volquartsen spring, on the other hand, promised a direct, mechanical correction. My immediate reaction was one of focused curiosity, eager to see if such a small part could indeed solve my shooting annoyance.

Real-World Testing: Putting Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV to the Test

First Use Experience

My testing grounds for this small but significant upgrade were the familiar confines of my local indoor range. The scenario was straightforward: a series of drills designed to mimic both casual plinking and slightly more focused target practice. My goal was to see if the added resistance from the Volquartsen spring would prevent accidental engagement of the safety during recoil or while I was actively manipulating the firearm.

During the initial rounds, I paid close attention to the feel of the safety lever. The difference was immediately apparent; it required a more deliberate press to move from “fire” to “safe.” This added resistance felt natural, not overly stiff, but certainly more positive than the factory setting.

I also wanted to see how the spring performed under repeated firing. I ran through several magazines of standard .22 LR ammunition, focusing on a steady rhythm. Even with the slight jar of recoil, the safety lever remained firmly in place, exactly where I intended it to be. There were no surprises or unexpected quirks; the intended function was precisely what I experienced.

Extended Use & Reliability

After several range trips, spanning well over a hundred rounds, the Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV has proven its worth. My Ruger MK IV, now equipped with this small upgrade, feels more secure in my hands during active shooting sessions. The peace of mind knowing the safety won’t inadvertently engage is a notable improvement.

In terms of durability, the spring shows no signs of wear. It’s a simple, robust component, and I don’t anticipate any premature failure. The increased resistance has remained consistent, with no loosening or degradation of its performance.

Maintenance has been virtually non-existent, as expected for a spring of this nature. The primary benefit of this specific upgrade is its ability to integrate seamlessly without requiring any complex cleaning or upkeep. Compared to the original spring, which perhaps had a lighter tension allowing for unintentional engagement, this Volquartsen unit offers a clear, albeit subtle, performance advantage.

Breaking Down the Features of Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV

Specifications

This particular component is a Safety Power Spring designed specifically for the Ruger Mark IV and Ruger Mark IV 22/45 pistol platforms. It is manufactured by Volquartsen Firearms in the USA. The primary function of this spring is to increase the force required to move the safety lever from the “fire” position to the “safe” position.

This increased tension directly addresses the issue of shooters inadvertently engaging the safety during the recoil phase of firing. The spring is a precision-engineered part, intended as a direct replacement for the factory component. Its compact size means it integrates without altering the overall ergonomics of the firearm.

Performance & Functionality

The primary job of the Volquartsen spring is to make the safety lever more resistant to accidental manipulation. It performs this function exceptionally well. The added tension is noticeable, providing a more solid detent for the safety lever, preventing it from being bumped out of the “fire” position.

Its strength lies in its simplicity and effectiveness. The main drawback, if one could call it that, is that it might make engaging the safety intentionally slightly more difficult for someone with very weak hands, though this is unlikely to be an issue for most shooters. For its intended purpose, it meets and exceeds expectations, providing a reliable solution to a common annoyance.

Design & Ergonomics

The design of the Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV is purely functional. It’s a small, robust spring crafted from quality materials, indicative of its USA origin. The finish is smooth, indicating good manufacturing standards.

Ergonomically, its impact is indirect but significant. By ensuring the safety lever stays put, it contributes to a more predictable shooting experience. There is no learning curve associated with this component; it simply works as intended once installed.

Durability & Maintenance

Given its simple construction and application, this spring is expected to last the lifetime of the firearm under normal use. It is a non-wearable part in the typical sense, unlike some other firearm components. There are no specific maintenance requirements beyond its initial installation.

The only potential “failure point” could theoretically be extreme overuse or improper installation, but for its intended use, this is highly unlikely. Its durability is a key selling point for such a small, specialized part.

Accessories and Customization Options

This specific product is a singular replacement part and does not come with any accessories. Furthermore, it is not designed for customization in itself; its purpose is to modify the function of the existing safety mechanism. Compatibility is strictly limited to the specified Ruger Mark IV models.

Pros and Cons of Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV

Who Should Buy Volquartsen Firearms Safety Pistol Power Spring Ruger MK IV?

This upgrade is ideally suited for Ruger Mark IV and Mark IV 22/45 owners who have experienced or are concerned about inadvertently engaging the safety lever during shooting. If you tend to have an aggressive grip or shoot with a pace that induces significant recoil movement, this spring will be a welcome addition. It’s for the shooter who appreciates fine-tuning their firearm for optimal performance and reliability during dynamic shooting.

Those who should probably skip this product are individuals who have never experienced an issue with their Mark IV’s safety lever.
