Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide Review

First Impressions of Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide

The Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide promises to be a significant upgrade for Glock enthusiasts looking to enhance their firearm’s performance and aesthetics. The Spinta Precision slide transforms a standard Glock 17 into a longer, competition-ready platform. Featuring an RMR cut, enhanced serrations, and a durable nitrided finish, it piqued my interest as a versatile option for both range use and potentially even some practical shooting scenarios.

I was driven to explore the Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide due to a growing desire to extend the sight radius of my Glock 17. I was aiming for improved accuracy at longer distances, a goal hindered by the standard slide’s shorter sight radius. The promise of a longer sight picture, combined with the ability to mount an RMR, pushed me towards giving this aftermarket slide a serious look.

Unboxing the slide, I immediately noted the clean machining and the deep black nitrided finish. The weight felt substantial, hinting at the quality of the 17-4 stainless steel used in its construction. It gave the impression of a well-made, durable component, ready to withstand the rigors of regular use.

I considered similar offerings from ZEV Technologies and Brownells before deciding on the Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide. The price point was a significant factor, as the Spinta Precision offering presented a compelling value proposition compared to the more expensive ZEV. The Brownells slide, while also attractive, lacked the specific aesthetic I was looking for in this build.

My initial reaction was excitement; this slide appeared to be exactly what I needed to take my Glock 17 to the next level. It seemed a great balance between performance-enhancing features, durable materials, and a reasonable price tag, fueling my anticipation for range testing.

Real-World Testing: Putting Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide to the Test

First Use Experience

My first range trip with the Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide was at an outdoor range on a moderately sunny day. I focused on shooting at distances ranging from 15 to 50 yards. The weather was mild, around 70 degrees Fahrenheit, with a slight breeze, offering ideal conditions for testing the slide’s impact on accuracy.

The slide performed admirably, noticeably improving my ability to acquire a clear sight picture. The longer sight radius immediately translated to tighter groupings at 25 yards. The enhanced slide serrations offered a more secure grip when racking, even with slightly sweaty hands.

Initially, I experienced a few failures to fully return to battery, which I attributed to the new slide needing to break in and mate with my existing Glock 17 frame. After about 50 rounds, these malfunctions disappeared entirely, and the slide ran smoothly for the remainder of the session.

Extended Use & Reliability

After several months of consistent use, the Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide has proven to be remarkably reliable. I estimate I’ve put over 1000 rounds through it without experiencing any further malfunctions. The slide continues to function flawlessly with a variety of ammunition types.

Durability has also been impressive. Despite regular use and occasional exposure to less-than-ideal conditions (minor dust and mud during an outdoor training session), the nitrided finish shows minimal signs of wear. The slide tracks smoothly on the frame rails, maintaining a tight fit.

Maintaining the slide has been straightforward. Regular cleaning and lubrication, following standard Glock maintenance procedures, has been sufficient to keep it running smoothly. I’ve found it no more difficult to clean than the original Glock slide. The Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide has exceeded my expectations, offering a tangible improvement in accuracy and handling compared to my stock Glock 17 slide.

Breaking Down the Features of Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide

Specifications

• The Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide is machined from 17-4 stainless steel, known for its high strength and corrosion resistance, ensuring long-term durability. This material choice is critical for withstanding the constant cycling and high pressures involved in firing a handgun.
• It is finished with a nitride coating, which increases the surface hardness and provides excellent resistance to wear and corrosion. The black nitride finish gives the slide a sleek, professional look while offering significant protection.
• The slide is designed for Glock 17L Gen 3 platforms, maintaining compatibility with existing Glock 17 Gen 3 frames and most internal components (excluding the barrel). This makes it a drop-in upgrade for those already familiar with the Glock platform.
• It features an RMR footprint sight cut, allowing for the direct mounting of Trijicon RMR and Holosun pistol red dot sights. This facilitates faster target acquisition and improved accuracy, especially at longer ranges.
• A skeletonized RMR cover plate is included, adding to the slide’s aesthetic while providing a protective cover when an optic is not mounted. The skeletonized design reduces weight without compromising structural integrity.
• The specifications state that the slide will come with 6-32×7/16in RMR screws, ensuring compatibility with most RMR pattern optics. These screws are specifically sized for the RMR cut, simplifying the optic mounting process.

Performance & Functionality

The Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide significantly enhances the performance of a standard Glock 17. The longer slide translates directly into an extended sight radius, making aiming easier and more precise, particularly at distances beyond 25 yards. The RMR cut allows for rapid target acquisition with a red dot optic, improving both speed and accuracy in dynamic shooting scenarios.

The slide’s primary strength lies in its ability to improve accuracy and sight acquisition speed. Its weakness, common to longer slides, is a slight increase in weight, which can affect handling for some users. It meets and, in some aspects, exceeds expectations for an aftermarket slide, providing tangible performance benefits.

Design & Ergonomics

The Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide boasts a well-thought-out design. The enhanced slide serrations provide a secure grip for racking, even in adverse conditions. The 17-4 stainless steel construction contributes to a solid, durable feel.

The design integrates seamlessly with the Glock 17 Gen 3 frame. The RMR cut is precisely machined for a snug fit with compatible optics. The learning curve is minimal, as the slide functions identically to a factory Glock slide, retaining the familiar ergonomics.

Durability & Maintenance

The Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide is built to last. The combination of 17-4 stainless steel and a nitride finish provides exceptional resistance to wear and corrosion. Regular cleaning and lubrication, consistent with standard Glock maintenance, will ensure a long service life.

Maintenance is relatively easy. The slide disassembles like a standard Glock slide, making cleaning and inspection straightforward. The nitride finish resists carbon buildup and wipes clean easily.

Accessories and Customization Options

The Spinta Precision Allegiance Glock 17L Gen 3 Pistol Slide ships with a skeletonized RMR cover plate and the necessary RMR mounting screws. The most significant customization option is the addition of a red dot optic. The RMR cut is compatible with a wide range of popular optics, allowing users to tailor the slide to their specific needs.

The slide is designed to work with standard Glock 17 Gen 3 internal components. This means that users can further customize their pistol with aftermarket triggers, guide rods, and other parts. It interfaces directly with most aftermarket Glock barrels chambered in 9mm.
