Blueline Magazine Extension for S&W M&P
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.
