First Impressions of Zaffiri Precision Glock 43 ZPS.2 RMSc Cut Complete Upper
The Zaffiri Precision Glock 43 ZPS.2 RMSc Cut Complete Upper promises to be a significant upgrade for Glock 43 and 43X owners looking to enhance their pistol’s performance and aesthetics. As someone who has spent over a decade working with tactical gear, I was immediately drawn to the promise of tighter tolerances and improved accuracy. This aftermarket complete upper, featuring an RMSc optic cut, immediately piqued my interest, as I’ve been seeking a more streamlined red dot setup for my concealed carry Glock 43.
My quest for a more accurate and versatile Glock 43 led me to the Zaffiri Precision Glock 43 ZPS.2 RMSc Cut Complete Upper. The factory Glock slide, while reliable, lacked the features I desired for modern shooting, such as an optic cut and enhanced serrations. I was tired of the limitations, wanting a more customized setup without the hassle of sending my factory slide off for milling.
Unboxing the upper was a premium experience. The slide, barrel, and internal parts were meticulously packaged, exuding quality craftsmanship right out of the box. The stainless steel slide felt substantial, and the Cerakote finish was flawlessly applied. Its weight inspired confidence, hinting at the precision engineering within.
Compared to similar offerings from Brownells and Agency Arms, the Zaffiri Precision upper struck a sweet spot in terms of price and features. Brownells’ slides offer value, but lack the same refined machining; Agency Arms delivers top-tier performance, but at a significantly higher cost. The Zaffiri Precision upper appeared to offer a compelling balance.
My initial impression was one of excitement. The Zaffiri Precision Glock 43 ZPS.2 RMSc Cut Complete Upper appears to be a well-engineered and aesthetically pleasing upgrade that I’m eager to test on the range. The included optic cover plate and compatibility with popular red dots like the Holosun 407k/507k are welcome additions that showcase thoughtful design.
