Product Overview:
Springer Precision 140mm magazine extension for Glock Mec-Gar 18rd magazines with a option for an extra power spring. It has added traction to the bottom to assist with reloads. The traction gives just enough texture in your palm to keep it from sliding. The unique locking mechanism allows a very solid attachment with a discrete set screw. They are specifically designed to work with our magwells and fit the USPSA 140mm magazine gauge. 

Custom engraved and custom colors are non-returnable

Please note: It's crucial to test and verify compatibility before using in competition settings, especially with 140mm/170mm magazine configurations. Variances can occur between mass-produced magazines, particularly in the magazine lips connecting with the extension/basepad.
