There Is Nothing Quite Like the Pairing of a Factory Firearm With a Factory Magazine The FN Herstal Magazine is a standard factory replacement magazine. This magazine is for Fn 509c Compact Models chambered in 9mm Luger and holds 10 rounds of ammunition. It is made from high quality alloy steel with a polymer follower and polymer base plate. The exterior of the magazine features a matte black finish. Additionally it is worth noting that the magazine is made to FN's specifications and tolerances, using the same manufacturing process and materials as the original equipment magazines which shipped with your firearm. This will ensure not only a perfect fit but exceptional operation.#html-body [data-pb-style="62DF828AA0BA3"]{justify-content: flex-start; display: flex; flex-direction: column; background-position: left top; background-size: cover; background-repeat: no-repeat; background-attachment: scroll; border-style: none; border-width: 1px; border-radius: 0px; margin: 0px 0px 10px; padding: 10px;}#html-body [data-pb-style="62DF828AA0BB0"]{border-style: none; border-width: 1px; border-radius: 0px; margin: 0px; padding: 0px;}
