Pearce Grip Grip Extension for Glock Gen 4 & 5 Model 27 & 27

The Pearce Grip Grip Extension for Glock Gen 4 & 5 Model 27 & 27 is a simple yet effective upgrade designed for shooters seeking improved ergonomics and control on a compact subcompact platform. This grip extension replaces the factory magazine base plate while retaining all original components, making it a non-invasive modification that requires no gunsmithing or permanent alteration. For law enforcement and civilian operators carrying the Model 27 as a duty or backup firearm, enhancing grip real estate directly translates to faster target acquisition and more controlled follow-up shots under stress.

The extension adds 5/8 inch of additional length to the magazine, extending the grip frame without increasing magazine capacity—a critical distinction for jurisdictions with magazine restrictions and for maintaining original reliability. By providing additional finger purchase on the lower three fingers, the grip extension reduces hand fatigue during extended shooting sessions and improves indexing consistency. The design maintains full compatibility with standard Glock Gen 4 and Gen 5 Model 27 magazines and does not interfere with holster fit when used with properly designed concealment or duty holsters. Installation is tool-free and reversible, allowing users to switch between extended and standard configurations based on mission requirements.

This grip extension is ideal for operators with medium to large hands who find the Model 27's compact profile uncomfortable for sustained control, or those transitioning from full-size duty weapons to backup platforms. Both sworn personnel and civilian defensive shooters benefit from the improved ergonomic control, particularly in high-stress scenarios where grip security directly affects accuracy and shot placement. The Pearce GripInc. design has proven itself in field use across law enforcement agencies, and this extension remains compatible with all Gen 4 and Gen 5 Model 27 magazines, ensuring seamless integration into existing ammunition and training ecosystems.
