Zaffiri Precision RTS Glock 19 Gen 5 ZPS.3 RMR Cut Slide Review

First Impressions of Zaffiri Precision RTS Glock 19 Gen 5 ZPS.3 RMR Cut Slide

The Zaffiri Precision RTS Glock 19 Gen 5 ZPS.3 RMR Cut Slide promises enhanced performance and a customized aesthetic for Glock enthusiasts. As someone with over a decade of experience in tactical gear and firearms, I was eager to evaluate its build quality, functionality, and real-world performance.

I was specifically looking for a slide that offered a reliable RMR cut and improved tolerances over the stock Glock slide. Several options existed, but the Zaffiri Precision slide stood out due to its ready-to-ship availability and reputation for quality machining. Upon unboxing, the slide’s Armor Black Cerakote finish appeared flawless, and the machining was crisp and clean, immediately instilling confidence. The slide felt solid, exhibiting a weight consistent with high-quality stainless steel. My initial thought was that this could be a significant upgrade over the factory slide, enhancing both the look and functionality of my Glock 19 Gen 5.

Compared to similar offerings from brands like Brownells and Agency Arms, the Zaffiri Precision slide offered a compelling balance of price and features. While Agency Arms slides are known for their aggressive styling, and Brownells offers a more budget-friendly option, the Zaffiri Precision slide seemed to hit a sweet spot with its clean design and ready-to-ship convenience. I was excited to see if its performance would match its promising first impression.

Real-World Testing: Putting Zaffiri Precision RTS Glock 19 Gen 5 ZPS.3 RMR Cut Slide to the Test

First Use Experience

My initial testing took place at an outdoor shooting range in varying conditions, from sunny afternoons to slightly drizzly mornings. I mounted a Trijicon RMR to the slide, using the provided screws and a touch of blue Loctite as recommended. The Zaffiri Precision slide felt immediately more precise than the factory slide when racking. I experienced consistent ejection patterns and a noticeably tighter lockup with my Gen 5 barrel.

The RMR sat snugly within the optic cut, and after zeroing, I was achieving significantly tighter groupings at 15 yards compared to my stock setup. During the drizzly morning, I paid close attention to grip and slide manipulation, noticing that the serrations provided ample traction even with wet hands. There were no immediate malfunctions, failures to extract, or any other issues during the first range session.

Extended Use & Reliability

After several months of consistent use, the Zaffiri Precision RTS Glock 19 Gen 5 ZPS.3 RMR Cut Slide has proven to be remarkably reliable. I’ve put approximately 1,500 rounds through it, using a variety of ammunition types. The Cerakote finish has held up exceptionally well, showing only minor signs of wear around the ejection port and high-friction areas.

Cleaning and maintenance are straightforward; a simple wipe-down with a solvent and light lubrication keep the slide running smoothly. The Zaffiri Precision slide consistently outperforms the stock slide in terms of accuracy and overall feel. I have experienced no failures to extract or feed issues, even with cheaper bulk ammunition. The improved tolerances are noticeable, contributing to a more consistent and predictable shooting experience.
