The Gun Company Combat Duty LVL-1 Glock 19 Gen 3 No Side Windows Stripped Slide Review

The Final Word on the The Gun Company Combat Duty LVL-1 Glock 19 Gen 3 No Side Windows Stripped Slide

As someone who’s spent over a decade pushing gear to its limits in diverse environments, from the controlled chaos of a workshop to the unpredictable elements of the field, finding the right components is paramount. My search for a custom slide for a Glock 19 Gen 3 project led me to The Gun Company Combat Duty LVL-1 Glock 19 Gen 3 No Side Windows Stripped Slide. It promised a blend of aggressive styling and functional serrations, a departure from the more common options. My goal was to build a reliable firearm that also made a distinct visual statement, and this stripped slide seemed to tick those boxes. I had considered some direct OEM replacements, but they lacked the aggressive aesthetic I was after. This particular offering from The Gun Company immediately sparked my interest due to its unique design elements. My initial impression upon unboxing was one of solid construction; the weight felt substantial, and the raw machining hinted at a robust build.

Real-World Testing: Putting The Gun Company Combat Duty LVL-1 Glock 19 Gen 3 No Side Windows Stripped Slide to the Test

First Use Experience

My initial testing of this stripped slide involved a thorough build process at my workbench. I paired it with a standard Glock 19 Gen 3 frame, a barrel, and all necessary internal components. The slide itself is designed as a bare component, requiring the builder to supply all internal parts, sights, and optics. I meticulously assembled everything, paying close attention to tolerances and fitment. During this build, I noticed the FAST chamfers provided a smooth transition, aiding in reassembly and initial slide racking. The barrel peep front nose scallop also contributed to a clean aesthetic as the barrel sat within the slide. My first range session focused on function-testing and initial zeroing of an RMR optic, mounted directly into the pre-machined cut. The Trijicon RMR optic cut was precisely machined, ensuring a secure and flush fit without any wobbling.

Extended Use & Reliability

Over several months, this build has seen consistent use on the range, typically during dedicated range days or informal practice sessions. I’ve put hundreds of rounds through it, experiencing a wide variety of ammunition types, from standard range fodder to defensive loads. The LVL-1 serrations at the 12, 3, and 9 o’clock positions proved exceptionally useful, particularly when performing press checks or clearing minor malfunctions under simulated stress. They offer a positive grip even with slightly damp hands, a common occurrence during longer shooting days. The slide has maintained its functional integrity, showing no signs of premature wear on the critical engagement surfaces. Cleaning is straightforward, as with any Glock slide; a simple field strip and a good cleaning kit suffice. I haven’t encountered any significant performance degradation or issues that would require specialized maintenance beyond routine cleaning. Compared to some other aftermarket slides I’ve utilized, this unit has held up remarkably well, especially considering its aggressive styling.

Breaking Down the Features of The Gun Company Combat Duty LVL-1 Glock 19 Gen 3 No Side Windows Stripped Slide

Specifications

This stripped slide is specifically designed for the Glock 19 Gen 3 platform, making it a direct fit for existing frames of that generation. It is fabricated from robust steel, promising durability for demanding applications. The slide is finished in a Black Cerakote, offering a degree of corrosion resistance and a non-reflective matte appearance. A key specification is the Trijicon RMR optic cut, a highly sought-after feature for modern pistol builds that allows for direct mounting of this popular red dot sight. The No Side Windows design contributes to a cleaner, more traditional profile while retaining aggressive functional elements.

Performance & Functionality

The primary function of a slide is to house the firing mechanism and guide the barrel during operation. This model excels in providing a stable and reliable platform for those functions. The LVL-1 Serrations are a standout feature, offering superior grip for manipulation of the slide, whether for racking, press checks, or clearing stoppages. These serrations are deep enough to be effective without being overly abrasive or snagging on clothing or gear. The 45 degree full length FAST chamfers on the slide edges contribute to a smoother draw from a holster and prevent sharp edges from catching. The barrel peep/lightning windows at 12:00, 3:00 and 9:00 not only lighten the slide slightly but also serve as visual indicators for barrel presence and alignment. This design choice enhances both functionality and a unique aesthetic appeal.

Design & Ergonomics

The design of the The Gun Company Combat Duty LVL-1 Glock 19 Gen 3 No Side Windows Stripped Slide is a clear departure from standard Glock slides, leaning into a more aggressive, custom look. The absence of traditional “window cuts” contributes to a sleeker profile, while the strategically placed LVL-1 serrations provide excellent tactile feedback. The machine engraved FREEDOM FLAG within the RMR cut is a subtle, yet striking, patriotic detail. The overall build quality feels solid, with precise machining evident throughout. The full length FAST chamfers contribute positively to the ergonomics, making the slide feel less sharp and more manageable during handling. The finish, a Black Cerakote, is applied evenly and has held up well against holster wear and general handling.

Durability & Maintenance

Given its construction from steel and the Black Cerakote finish, this stripped slide is built for longevity. Steel is inherently more durable than aluminum alloys often found in some aftermarket slides, offering greater resistance to impact and wear. The Cerakote finish, while not impervious to damage, provides a good barrier against corrosion and minor abrasions. Regular cleaning and lubrication, as with any firearm component, will ensure optimal performance and extend its service life. I have not experienced any issues with the finish flaking or showing excessive wear despite consistent use and occasional rough handling. The precision machining of the RMR cut means that once an optic is mounted, it should remain secure, contributing to the overall durability of the optic-slide system.

Accessories and Customization Options

As a stripped slide, The Gun Company Combat Duty LVL-1 Glock 19 Gen 3 No Side Windows Stripped Slide is, by definition, a component requiring significant assembly. This means the user must procure all necessary internal parts, including the extractor, firing pin, striker, channel liner, and recoil spring assembly. Crucially, the Trijicon RMR optic cut means you will need an RMR footprint optic and the corresponding mounting screws. Additionally, appropriate front and rear sights that are compatible with the Glock 19 platform and will co-witness with an RMR are essential. The availability of these components is widespread within the firearm aftermarket, allowing for significant customization of the final build. The machine engraved FREEDOM FLAG is a permanent aesthetic feature that cannot be altered.
