The angled serrations provided a positive grip during manual manipulations, even with slightly damp hands. There were no immediate issues with feeding or ejection, which is always a good sign for a new slide.

However, the user feedback I encountered mentioned cycling issues with Gen 5 Glocks, and I unfortunately experienced this firsthand. When paired with a ZEV barrel, the firearm would not cycle reliably. This was a surprise, as I had anticipated a seamless integration given the ZEV components. This particular issue required further investigation and interaction with the manufacturer.

Extended Use & Reliability

After several range sessions and approximately 500 rounds through the ZEV Technologies Z17 Citadel Stripped Slide w/RMR Plate, its core functionality as a slide remains solid, though the cycling issue with certain barrel pairings is a significant caveat. The 17-4 stainless steel construction has proven durable, with no signs of galling or excessive wear, even with frequent cleaning and reassembly. The lowered ejection port appears to function as intended, aiding in consistent brass ejection without interference. The finish, whether DLC or PVD, shows a remarkable resistance to scratches and holster wear, maintaining its aesthetic appeal.

Maintenance is straightforward; the slide disassembles easily from the frame, and the channel liner installed by ZEV is a welcome feature that simplifies assembly. Compared to other aftermarket slides I’ve used, the tolerances on this ZEV offering are indeed tighter, contributing to a stable barrel lockup. However, the documented performance issues with specific barrel combinations detract from an otherwise excellent product. The need for careful pairing to ensure reliable function is a crucial consideration for potential buyers.

Breaking Down the Features of ZEV Technologies Z17 Citadel Stripped Slide w/RMR Plate

This monolithic construction ensures consistent material properties throughout the slide. It is designed for Glock 17 platforms, specifically accommodating 9mm Luger ammunition. A key feature is the Trijicon RMR optic cut, which is machined to precise tolerances and includes ZEV’s patented optic cut system with posts for increased thread area, ensuring a secure mount for your red dot sight. The slide also comes with an RMR Cover Plate, a useful addition for when an optic is not mounted.

These specifications translate directly into tangible benefits for the end-user. The 17-4 stainless steel ensures longevity and resistance to the rigors of use, while the tight manufacturing tolerances contribute to improved accuracy by providing a more consistent lockup with the barrel. The patented optic cut design is a critical feature for those looking to mount a red dot, offering enhanced security for the optic compared to some other mounting solutions. The inclusion of a cover plate adds versatility, allowing the user to run the pistol either with or without an optic without compromising the slide’s aesthetics or protection.

Performance & Functionality

At its core, the ZEV Citadel slide is designed to enhance a pistol’s performance, primarily through improved accuracy and reliability. The match-grade, precision milled tolerances are noticeably tighter than those found on factory slides. This tighter fit contributes to more consistent barrel lockup, which in turn can lead to improved grouping performance. The angled serrations on the slide are not just for aesthetics; they provide a very positive grip for slide manipulation, whether performing a press check or dealing with malfunctions.

The slide’s lowered ejection port is designed to improve brass ejection, potentially reducing instances of stovepipes or other ejection-related malfunctions. This feature, combined with the overall tight tolerances, aims to create a more reliable firearm. However, as noted in my testing, the interaction with specific ZEV barrels on a Glock 17 Gen 5 can introduce cycling issues, which is a significant detractor from its otherwise stellar performance potential. This suggests that while the slide itself is well-engineered, perfect harmony across all components is not always guaranteed.

Design & Ergonomics

The ZEV Technologies Z17 Citadel Stripped Slide w/RMR Plate showcases a thoughtful and functional design. The angled serrations are ergonomically placed, offering excellent purchase for both forward and rearward cocking techniques. They feel aggressive enough to provide grip without being uncomfortable during handling. The slide channels on top are specifically engineered to reduce glare, a subtle but appreciated feature that aids in maintaining a clear sight picture, especially under bright lighting conditions.

The overall build quality is exceptional, reflecting ZEV Technologies‘ commitment to premium manufacturing.
