The FN 509 Midsize MRD is a 9mm striker-fired pistol in Flat Dark Earth, with a 4-inch barrel and a 7.4-inch overall length. It weighs 25.5 ounces and holds 10+1 rounds with two 10-round magazines included. The slide uses FN's Low Profile Optics Mounting System for compatible miniature red dot optics, and black co-witness iron sights are fitted. The flatter-faced trigger and interchangeable textured backstraps complete the grip and control setup.

The midsize frame balances concealed-carry portability with shooting control, which suits a buyer who wants a pistol that can be carried and still handled well at the range. Fully ambidextrous controls accommodate left- and right-handed use. The page notes that the pistol accepts larger-capacity FN 509 magazines when used with the appropriate sleeve. State rules on magazine capacity apply, so check them before purchase.
