The Ghost Mag Extension for Glock 42 is a drop-in magazine extension that increases your standard Glock 42 magazine capacity by two rounds without requiring permanent modification or baseplate replacement. This accessory uses the existing Glock factory baseplate, making installation straightforward for operators who need discrete capacity gains on this compact, single-stack platform.
The extension incorporates a chrome silicon magazine spring engineered to maintain reliable feeding and extraction across the Glock 42's operational envelope. The two-round addition is meaningful for a subcompact carry gun—that's roughly a 25% boost to baseline capacity, a difference that matters in defensive scenarios where follow-up shots may be necessary. The compact dimensions (2.25 x 1.25 x 6.75 inches) ensure the extended magazine remains compatible with standard Glock 42 holsters and carry systems designed for the factory configuration, a critical consideration for duty and concealed carry applications where holster fit directly affects draw speed and retention.
This extension suits backup officers, plainclothes carriers, and shooters who prioritize concealability but want tactically relevant ammunition reserves. The Glock 42 platform is popular in deep-concealment and off-duty roles where size constraints outweigh capacity ideals, making this extension a practical middle ground. Installation requires no gunsmithing, and the design preserves the original baseplate geometry for consistent handling and magazine manipulation under stress.
Ghost Inc. extensions represent a straightforward, proven approach to magazine capacity optimization within the constraints of compact single-stack platforms. This product is ideal for shooters seeking verified, field-tested capacity solutions without custom modifications or compatibility risk.
