Cross Armory CRG+5MEG17BK +5 Magazine Extension Glock 17 Gen 1-5 Black Aluminum

The Cross Armory +5 Magazine Extension is a precision-machined aluminum baseplate extension designed to add 5 additional rounds of capacity to factory Glock 17 Gen 1-5 pistol magazines. The CRG+5MEG17BK installs in place of the factory baseplate, extending the magazine body to provide meaningful extra round count without requiring entirely new magazines.

Built from lightweight black aluminum, this extension is engineered to maintain a comfortable grip profile while adding usable length to the magazine. Cross Armory magazine extensions are designed for straightforward installation on existing Glock 17-pattern magazines, making this a practical upgrade for range and training setups where additional capacity is desired.
