As a seasoned tactical gear specialist, I’m always looking for ways to improve the performance of my firearms. I was seeking a slide upgrade to improve my Glock 19’s accuracy and accommodate an RMR optic.
Upon unboxing, the slide exuded a sense of quality. The black Cerakote finish was smooth and even, and the machining appeared precise.

Real-World Testing: Putting Zaffiri Precision RTS G19 ZPS.6 Slide to the Test
First Use Experience
I first tested the Zaffiri Precision RTS G19 ZPS.6 Slide at my local shooting range. I used a variety of ammunition to assess its performance, including 115 grain FMJ, 124 grain +P, and 147 grain subsonic rounds. The weather was typical for early spring—cool and slightly damp.
The slide cycled smoothly with all ammunition types. There were no failures to feed or eject during the first 200 rounds. The RMR cut was precisely machined, allowing for a secure and repeatable optic mount.
The initial surprise was the noticeable improvement in accuracy. Groupings tightened up considerably compared to the stock slide, especially at distances beyond 15 yards. I also found the enhanced grip serrations easier to manipulate, even with wet hands.
Extended Use & Reliability
After several months of consistent use, the Zaffiri Precision RTS G19 ZPS.6 Slide has proven to be a reliable upgrade. It has seen approximately 1000 rounds without any malfunctions. The slide has held up well to regular use.
There are no significant signs of wear and tear on the Cerakote finish. Regular cleaning and lubrication have kept the slide functioning smoothly. The slide is relatively easy to clean. I typically use a solvent and brush to remove carbon buildup, followed by a light coat of oil.
Compared to my previous experience with the factory Glock slide, the Zaffiri Precision slide has outperformed it in every measurable aspect. The increased accuracy, improved grip, and optic compatibility make it a significant upgrade. I am very happy with the results.
