Breaking Down the Features of Zaffiri Precision Glock 17 Gen 3 ZPS.3 Threaded Complete Upper
Specifications
The Zaffiri Precision Glock 17 Gen 3 ZPS.3 Threaded Complete Upper boasts several key specifications. It features a single billet 17-4 stainless steel slide. This material provides excellent strength and corrosion resistance.
The slide is cut for a Trijicon RMR / SRO, Holosun 407c / 507c, and other popular RMR footprint optics. This allows for easy mounting of a red dot sight. The threaded barrel is made from high-quality steel and is ready for a suppressor or compensator.
The complete upper includes all necessary internal parts, such as a striker, extractor, and firing pin safety. The optic cut is located in front of the factory rear sight dovetail, preserving the ability to use iron sights as a backup. The slide also comes with proper mounting screws and a black anodized cover plate for the optic cut.
The manufacturer is Zaffiri Precision. The upper is designed for the Glock 17 Gen 3 platform. The optic cut is specifically an RMR Cut. The color is a striking Gold/Black combination. Note that no magazine is included.
These specifications contribute to improved accuracy, reliability, and customization options. The stainless-steel construction ensures durability, while the RMR cut allows for enhanced aiming capabilities.
Performance & Functionality
The Zaffiri Precision Glock 17 Gen 3 ZPS.3 Threaded Complete Upper significantly improves the performance of a standard Glock 17. The tighter tolerances of the slide and barrel increase accuracy. Follow-up shots are faster and more consistent.
The improved slide serrations provide a more secure grip for racking the slide. This is especially helpful in adverse conditions or when wearing gloves. The threaded barrel allows for the use of muzzle devices to reduce recoil and muzzle flip.
One minor weakness is that the gold finish can be prone to scratching if not handled carefully. However, this is purely cosmetic and does not affect the functionality of the upper. It meets and exceeds expectations.
Design & Ergonomics
The Zaffiri Precision upper is designed with both aesthetics and ergonomics in mind. The aggressive slide cuts give the pistol a modern and distinctive look. The weight is similar to the factory Glock slide.
The enhanced grip serrations make the slide easier to manipulate. The RMR cut is precisely machined and allows for a seamless integration of red dot sights. The upper is user-friendly and requires no special tools or gunsmithing skills to install.
Durability & Maintenance
The Zaffiri Precision Glock 17 Gen 3 ZPS.3 Threaded Complete Upper is built to last. The stainless-steel construction ensures excellent corrosion resistance. With proper care and maintenance, it should provide years of reliable service.
