Volquartsen Firearms V-Lock Retainer Ruger MK IV and Ruger MK IV 22/45 Review

First Impressions of Volquartsen Firearms V-Lock Retainer Ruger MK IV and Ruger MK IV 22/45

The Volquartsen Firearms V-Lock Retainer Ruger MK IV and Ruger MK IV 22/45 is a seemingly simple, yet potentially crucial, upgrade for anyone who owns a Ruger MK IV or MK IV 22/45 pistol. The Volquartsen name is synonymous with quality and performance in the rimfire world, and I was eager to see if this tiny part lived up to that reputation. This small piece aims to solve a common annoyance – the bolt stop cross pin drifting out during extended shooting sessions.

As an avid Ruger MK IV enthusiast, I’ve experienced the frustration of the bolt stop cross pin working its way out mid-session. It’s a minor inconvenience, but one that can interrupt the flow of shooting and, if lost, render the pistol temporarily unusable. I was searching for a reliable, non-permanent solution to this problem, and the V-Lock Retainer seemed promising.

Upon receiving the V-Lock Retainer, my first impression was that it’s a very small, precisely machined part. The finish was clean, and the overall build quality appeared excellent, as expected from Volquartsen Firearms. Compared to other DIY fixes I’ve considered, such as using thread locker or creating a custom retention system, the V-Lock Retainer offered a much more elegant and professional solution.

I chose this product over other potential fixes because of its simplicity and the manufacturer’s reputation. I was excited to install it and test its effectiveness at preventing the pin from walking out, and hoped it would be a lasting fix. My initial excitement was tempered with a bit of skepticism – could something so small really make a difference?

Real-World Testing: Putting Volquartsen Firearms V-Lock Retainer Ruger MK IV and Ruger MK IV 22/45 to the Test

First Use Experience

My first opportunity to test the Volquartsen Firearms V-Lock Retainer Ruger MK IV and Ruger MK IV 22/45 came during a steel challenge match at my local shooting range. I ran approximately 500 rounds through my Ruger MK IV 22/45 Lite, a pistol known for its light weight and, consequently, increased recoil compared to heavier models. Installation was straightforward, requiring removal of the hammer as stated in the product description.

The weather was dry and sunny, ideal for shooting, and I paid close attention to the bolt stop cross pin throughout the match. Typically, I would have noticed some movement of the pin after a couple of magazines. However, after the entire match, the pin remained firmly in place, a testament to the V-Lock Retainer’s effectiveness.

The installation instructions provided clear guidance, and I didn’t encounter any unexpected challenges. I was pleasantly surprised by how such a small part could make such a noticeable difference.

Extended Use & Reliability

After several months of regular use, including weekly range sessions and a rimfire training course, the Volquartsen Firearms V-Lock Retainer Ruger MK IV and Ruger MK IV 22/45 continues to perform flawlessly. There are no signs of wear and tear on the retainer itself, and the bolt stop cross pin remains securely in place. The peace of mind this little part provides is well worth the minimal investment.

Maintenance is essentially non-existent; there’s nothing to clean or adjust. I simply field strip my Ruger MK IV after each shooting session, clean the bore and other components, and reassemble, with the V-Lock Retainer remaining untouched. Compared to my previous routine of constantly checking and occasionally re-seating the bolt stop cross pin, this is a massive improvement.

This little upgrade has significantly outperformed my expectations. It’s a simple, elegant solution to a common problem, and it has proven to be both durable and reliable.
