ProMag FNHA1FDE 20rd 5.7x28mm Fits FN Five-seveN FDE Polymer

Description

This is a ProMag 20-round 5.7 x 28 mm magazine.

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 sold into California, Connecticut, Illinois, Maryland, New Jersey, New York and the District of Columbia. 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.

The ProMag 20rd Fits FN is a magazine. A magazine holds cartridges and feeds them into the chamber. Body, follower and spring are matched to one cartridge and usually to one gun. Capacity and chambering both have to match. Cartridges differ in length and case shape, so a magazine built for one will not feed another reliably even where it physically fits. Capacity is restricted in some states and cities, and the limit is on possession, not only sale. Check your local rules before ordering – if you are unsure, ask us first. This is a part or accessory, not a firearm, and ships directly to your address.
