Pearce Grip 1045+ Extension GLOCK 29/20/21/40/41 Magazine Extension

The Pearce Grip 1045+ Extension for GLOCK 29/20/21/40/41 magazines addresses a critical gap in firepower accessibility for duty and defensive shooters. Law enforcement and armed citizens running GLOCK's compact .45 ACP and 10mm platforms often face limited round capacity in standard factory magazines. This extension adds critical rounds to your magazine stack without requiring a full pistol platform change, enabling faster magazine rotations during training or extended operational scenarios. The 1045+ is engineered for shooters who demand reliability without compromise—those familiar with ballistic stress and the real-world pressure of sustained engagements.

Pearce Grip manufactures this extension using proven polymeric materials that withstand the cyclic loading inherent in semi-automatic magazine operation. The extension's design increases magazine depth while maintaining the dimensional tolerance stack critical for reliable chambering and ejection cycles. The compact footprint—measuring 2.7 x 1.4 x 4 inches and weighing just 0.05 lbs—ensures minimal impact on your carry profile or equipment weight budget. Installation is straightforward: the extension slides over the magazine body tube and locks into place, requiring no gunsmithing or specialized tools. This no-gunsmithing approach means operators can field-deploy the upgrade immediately, making it ideal for those transitioning between magazines or running mixed magazine pools across teams.

The Pearce Grip 1045+ Extension is compatible with original factory GLOCK magazines for the 29, 20, 21, 40, and 41 models—covering both subcompact 10mm and full-size .45 ACP lineups. Those running 10mm duty loads, .45 ACP tactical carbine courses, or defensive ammunition testing will benefit most from the added capacity. Military and law enforcement armors favor Pearce extensions for fleet upgrades because they don't require magazine replacement, preserving inventory investment.
