KelTec, a familiar firearm brand amongst airsoft enthusiast known for unconventional yet often ingenious designs, has announced its latest creation: the SUB2000 GLK chambered in the 10mm Auto cartridge. This addition to the third-generation SUB2000 series is a significant one, as it answers the call for a pistol-calibre carbine that delivers not only on the promise of portability but also on the potent capabilities inherent in the 10mm round.

By seamlessly integrating Glock 20 magazine compatibility with its signature folding mechanism, KelTec has crafted a firearm that warrants serious consideration across a spectrum of applications, from safeguarding the home to providing a reassuring presence in the backcountry.

The distinct feature of the SUB2000 lineage, is the ingenious folding mechanism, has been refined in this 10mm variant. The rotating forend, a hallmark of the third generation, allows the carbine to neatly fold in half, achieving an unparalleled degree of compactness without needing the removal and potential zeroing issues associated with detached optics. This thoughtful design offers users a firearm that can be discreetly stowed and rapidly deployed when the need arises. Complementing this core feature are the now-standard modular M-LOK slots and Picatinny rails for the attachment of lights, lasers, and other mission-essential accessories.

The 10mm round, initially conceived for law enforcement and later embraced by discerning civilian shooters, boasts a significant increase in velocity and energy compared to its more mainstream counterparts. This translates to enhanced ballistic performance, offering improved accuracy and terminal ballistics, particularly at extended ranges facilitated by the SUB2000 GLK's 16.25-inch barrel. This longer barrel not only maximizes the potential of the 10mm cartridge but also contributes to a more stable and controllable shooting platform, making it a compelling option for those who demand both power and precision. Furthermore, the inclusion of a threaded barrel opens the door for suppressor integration, adding another layer of versatility for tactical applications and sound-sensitive environments.

While maintaining the core design ethos of its predecessors, the SUB2000 GLK 10mm exhibits a minor but necessary increase in weight, tipping the scales at approximately 5.6 pounds. This marginal heft is a direct consequence of the reinforced construction required to safely and reliably handle the higher pressures generated by the potent 10mm cartridge. According to the company, despite this added mass, the carbine remains commendably manageable, striking a balance between robustness and user-friendliness. The ergonomics, refined through earlier iterations, ensure a comfortable and intuitive shooting experience, allowing for confident handling and accurate shot placement.

A key element of KelTec's design philosophy is the intelligent integration of widely available and trusted magazine systems. In the case of the SUB2000 GLK 10mm, the compatibility with Glock 20 magazines is a significant advantage. These magazines, are known for their reliability and readily available in a standard 15-round capacity, provide users with a familiar and dependable feeding system. Moreover, the carbine's ability to accept various third-party stick and drum magazines further enhances its adaptability, catering to users who may already have a significant inventory of such accessories or require higher capacity options for specific scenarios.

Priced at a manufacturer's suggested retail price of $599, the SUB2000 GLK 10mm occupies a slightly higher price point compared to its siblings chambered in other calibers. This pricing reflects the added engineering and material considerations necessary to accommodate the more powerful 10mm cartridge, as well as the enhanced capabilities it offers. 

Scheduled for availability in the summer of 2025, this new offering is poised to attract a diverse clientele, ranging from law enforcement and security professionals looking for a compact yet potent carbine to outdoor enthusiasts desiring a capable sidearm companion in bear country, and recreational shooters looking for a unique and powerful platform.

KelTec's SUB2000 GLK 10mm blends the virtues of compactness, which is a hallmark of the SUB2000 series, with the substantial power and versatility of the 10mm Auto cartridge. Its ability to rapidly transition from a discreetly folded package to a fully operational firearm underscores its adaptability in dynamic situations. Whether deployed from a vehicle, a backpack, or within the confines of a home, the SUB2000 GLK 10mm offers a compelling combination of portability and firepower that is difficult to ignore.

However, as with any firearm, prospective owners must carefully consider the specific characteristics of the SUB2000 GLK 10mm. The slightly increased weight, while contributing to stability, may be a factor for individuals prioritizing absolute lightweight portability. Ultimately, the SUB2000 GLK 10mm is a step forward for KelTec in delivering a compact and potent package that expands the possibilities for pistol-calibre carbines in the modern firearms landscape.
