The FN 509 Compact is a striker-fired 9mm pistol with a polymer frame, a 3.7-inch barrel and a 6.8-inch overall length. It weighs 25.5 ounces and holds 10+1 rounds, with two magazines included. Interchangeable backstraps let you change the grip size. Standard fixed sights and an integrated trigger safety are fitted, and the black finish has a subdued look.
The compact frame and short barrel position this model for concealed carry and everyday defensive use, as the supplier describes. The backstraps help the grip fit different hand sizes, and the fixed sights offer a familiar picture without a red dot. A 10+1 capacity balances round count with the compact profile. The black finish is listed as subdued, and the integrated trigger safety supports secure handling during carry.
