FAB Defense Glock 17/19 COBRA Quick-Deployment Folding Stock

FAB Defense Glock 17/19 COBRA Quick-Deployment Folding Stock

The FAB Defense COBRA is a lightweight folding stock system designed for compatible Glock pistols, including the Glock 17 and Glock 19. It attaches at the rear of the pistol grip without permanent modification and adds a rapidly deployable shoulder stock while leaving the handgun's slide, controls, and accessory rail exposed.

Unlike a full pistol conversion chassis, the COBRA focuses specifically on rear support. The stock folds alongside the handgun for a compact profile and can be extended from the folded position into a full-length deployed stock. Replaceable adapters allow the system to fit supported Glock frame configurations across Gen 2 through Gen 5.

Quick-Deployment Folding Design

The defining feature of the COBRA is its folding rear assembly. When folded, the stock remains alongside the pistol to reduce the overall profile. The deployment mechanism allows the stock to extend into its full-length position when shoulder support is required.

An integrated cheek rest and high-traction rubber buttpad provide additional contact points once the stock is deployed. Because the COBRA attaches directly at the rear of the grip rather than enclosing the firearm, the pistol's slide, sights, controls, and accessory rail remain directly accessible.

Glock Compatibility

FAB Defense lists the COBRA as compatible with the following Glock models in supported Gen 2 through Gen 5 configurations:

• Glock 17
• Glock 19
• Glock 19X
• Glock 22
• Glock 23
• Glock 24
• Glock 25
• Glock 31
• Glock 32
• Glock 34
• Glock 35
• Glock 45

The system uses replaceable adapters to accommodate supported Glock 17 and Glock 19 frame configurations. FAB Defense also states that the Glock 17 Gen 4 adapter fits certain full-size polymer-frame IWI Jericho models, including the PL, RPL, and PSL.

Fitment Note: Buyers should confirm their exact pistol model, generation, and grip configuration before installation.

COBRA vs. Full Pistol Conversion Chassis

The COBRA is a different type of product from a full chassis system such as the FAB Defense KPOS Scout. It does not surround the pistol or add an external optics rail, charging handle, or accessory chassis. Instead, the COBRA is designed specifically to add a compact folding shoulder stock while retaining the pistol's original operating layout.
