PROMAG SIG MPX 9MM 50RD DRM BLK POLY

Description

This is a ProMag 50-round 9mm magazine for the Standard, in Black.

This is an extended magazine, adding rounds at the cost of some grip length and concealability. Magazines are consumable: springs and followers wear before the body does, so buying spares and rotating them is cheaper than chasing feed problems later.

Please note this item cannot be shipped directly to California, Rhode Island and Washington and cannot be sold into Illinois and Oregon. Restrictions come from the manufacturer or distributor and are applied automatically at checkout, so check before ordering if you are in one of those states. Magazines ship directly to you with no FFL transfer.

ProMag magazines are made in the USA and backed by a lifetime guarantee against manufacturer's defects. Magazine springs are precision wound using heat-treated chrome silicon wire and each and every step of the assembly process is checked and double checked in order to maintain the same consistent level of quality.
