FN 509 Midsize MRD: The Evolution of Everyday Carry

The FN 509 Midsize MRD is a testament to the evolution of concealed carry pistols, combining innovation with practicality. This firearm stands out as an exemplary choice for those seeking reliability and versatility in their everyday carry (EDC) weapon.

At its core, the FN 509 Midsize MRD boasts a robust four-inch barrel paired with a slide that accommodates an optics mounting package. This feature allows you to directly mount more than ten different miniature red dot sights, enhancing your targeting precision without compromising concealability.

The pistol's midsized frame houses a standard magazine capacity of 10+1 rounds. However, it does not stop there; this model remains compatible with larger capacity magazines from the FN 509 series when used with an appropriate sleeve. Such adaptability ensures you are always prepared, whether on duty or during daily personal defense scenarios.

Ergonomics have been meticulously considered by incorporating improved controls that facilitate easy manipulation under stress. Additionally, two included backstraps offer enhanced texturing for superior recoil management—ensuring stability shot after shot.

A significant upgrade comes in the form of its new flatter-faced trigger design. This improvement promotes a controllable trigger press and delivers a cleaner break—a crucial factor in maintaining accuracy during rapid engagements.

The FN Low Profile Optics Mounting System further refines this platform by providing seamless integration options for popular optics brands while keeping your sight picture low and unobstructed.
