Blueline Magazine Extension +3 - Black

Blueline Magazine Extension +3

Smith & Wesson M&P 9/40

Designed in collaboration with a current SWAT Operator and US Army Veteran, our Magazine Extensions offer:           

Confident magazine indexing through our patent pending design.

Improved grip support for shooters with larger hands.

Basepad allows for an effortless strip with the knife-edge of the support hand on malfunctions or stuck magazines.

Designed by a door-kicker, for door-kickers.

The kit comes with the magazine extension only, through extensive testing we have found a longer spring unnecessary.
