Tried and true, the FN 509 Compact has “been there and done that.” That’s exactly why we chose it as one of our best 9mm compact handguns. Capacity on the 509 Compact is above average, with 12 rounds in the standard magazine and 15 in the extended (where legal). There’s a MIL-STD 1913 rail for your lights, lasers, or whatever other pistol accessory you want. This one also has a fully ambidextrous slide stop lever and magazine release. The grip frame is modular.
Fun fact: the FN 509 Compact can accept all higher capacity FN 509 magazines, including those for the 17 and 24-round magazines seen on Tactical and Edge models (again, where legal).
