Description
Picture this: you need a compact, powerful tool for home defense or a discreet truck gun that can be deployed in seconds, not minutes. You need something that folds down to the size of a briefcase but fires a serious .40 S&W cartridge. That’s the exact scenario the Keltec Sub-2000 G2 .40 S&W, 16.25″ Barrel, Gator Grip, M-LOK, OD Green, 15rd is built for. It’s a takedown carbine that folds in half for maximum portability and unfolds to a ready-to-fire state in under three seconds.
Here’s the thing—this isn’t a range toy. It’s a practical, action-ready firearm designed for real-world utility. The G2 model brings significant upgrades, most notably the aggressive Gator Grip texturing that gives you a solid, non-slip hold in all conditions. The 16.25-inch barrel provides excellent velocity for the .40 S&W round, making it a potent option for defensive use. At a weight of just over 4 pounds, it’s easy to maneuver in tight spaces, a critical factor when every second counts.
Key Features
The standout feature is the folding mechanism. The barrel and action rotate 180 degrees to fold flat alongside the receiver, reducing the overall length to a mere 16.25 inches—the same length as its barrel. This makes it incredibly easy to stow in a backpack, vehicle console, or compact safe. When you need it, a simple twist and pull extends it to its full, locked position. No gunsmithing required; it’s drop-in ready from the box.
The M-LOK handguard is a major upgrade. It allows for direct attachment of lights, lasers, and vertical grips without bulky adapters, letting you customize your setup for low-light home defense. The OD Green finish isn’t just for looks; it provides a low-visibility profile in many outdoor environments. This model is specifically designed to accept Glock .40 caliber magazines, offering reliable feeding and compatibility with a vast ecosystem of proven, high-capacity magazines you may already own.

Pros & Cons
Pros: Unmatched portability due to the folding design. The .40 S&W caliber delivers solid stopping power in a lightweight platform. The M-LOK system and Gator Grip provide modern ergonomics and customization. Magazine compatibility with common Glock models simplifies logistics and training. At $519.25, it offers unique functionality at a competitive price point.
Cons: The sight picture is basic. The charging handle is non-reciprocating but can be stiff for some users. As a direct blowback firearm, recoil is more pronounced than a piston-driven system, though manageable. The folded profile, while compact, is not as slim as some other takedown designs.
Who It’s For
This carbine is for the Missouri resident who values practical solutions. It’s for the homeowner seeking a capable, compact carbine for property defense that can be securely stored in a small space. It’s for the prepared individual who needs a discreet, packable firearm for backcountry travel or as a vehicle emergency tool. It’s also an excellent choice for a shooter who already uses Glock pistols in .40 S&W and wants a long gun that shares magazine commonality.
Frequently Asked Questions
Q: What Glock magazines does this model use?
A: This specific .40 S&W model is compatible with Glock 22 and Glock 23 magazines. It comes with one 15-round magazine, and you can use any aftermarket or OEM Glock-pattern magazine in .40 S&W.
Q: Is an optic easy to mount on the Sub-2000 G2?
A: Yes, but it requires a specific approach. Because the rifle folds, a standard top-mounted optic would be in the way. The best solutions are optics mounted on the M-LOK handguard via a side mount or using a quick-detach (QD) optic on the receiver that can be removed before folding.
Q: What is the process for purchasing this online?
A: All firearm purchases from firearms-missouri.com require an FFL transfer. You can have this Keltec Sub-2000 shipped to a licensed FFL dealer in Missouri or any other compliant US state for the required background check and pickup.
