Warne 3306 Magazine Extension Black, +3 (9mm Luger), +4 (40S&W), for S&W M&P 9/40

Description

This is a Warne 2-round 9mm magazine for the Magazine Extension, in Black.

A magazine of this capacity is typical of compact and single-stack pistols, where a slimmer grip matters more than round count. Magazines are consumable: springs and followers wear before the body does, so buying spares and rotating them is cheaper than chasing feed problems later.

Several states and cities cap magazine capacity, and those limits change. Check your state and local rules before ordering – we ship to your address or your dealer, but we cannot ship a magazine somewhere it is not legal. Magazines ship directly to you with no FFL transfer.
