For shooters seeking a controllable, cost-effective pistol for training, plinking, or light-range defense drills, a .22 rimfire semi-auto that mirrors full-size ergonomics can be a game-changer. A purpose-built rimfire that accepts optics and fits familiar holsters shortens the transition from practice to primary carry platforms while keeping operating costs low.

FN 502 MRD [BLK]

Overview

The FN 502 MRD [BLK] blends the affordability of the .22 rimfire cartridge with the signature ergonomics of FN Herstal’s 500 series handguns. It ships with an optics-ready slide and suppressor-height iron sights, making it straightforward to mount micro red dots while retaining co-witnessed backup sights. Ambidextrous controls and cross-compatibility with most FN 509 holsters broaden the user base, and the package includes two 10-round magazines. Priced at $380.99, this model brings training realism without breaking the budget.

Design & Controls

Ergonomics and Handling

The grip geometry follows the FN 500 family layout, so shooters familiar with the series will recognize the controls and hand fit. Ambidextrous slide stop and reversable features ensure left- and right-handed shooters can operate the pistol without compromise. The all-black frame presents a low-profile footprint for range use and storage.

Optics-Ready Slide & Sights

The optics-ready slide simplifies dot installation for fast target acquisition. Suppressor-height iron sights are useful when a red dot is mounted or when using a suppressor-height optic, maintaining sighting options in multiple configurations. Compatibility with many FN 509 holsters means you can test carry setups without extensive gear changes.

Range Use and Ammunition

The .22 rimfire platform is ideal for low-recoil marksmanship drills, high-volume practice, and economical range sessions. Ammunition costs and reduced recoil allow shooters to refine fundamentals—trigger control, sight picture, and follow-through—without the fatigue associated with centerfire rounds. For instructors and trainers, the FN 502 MRD [BLK] is an efficient training tool that mirrors service-pistol ergonomics.

Buying Considerations

At $380.99, the FN 502 MRD [BLK] offers a compelling balance of affordability and feature set. It’s best suited for shooters who want realistic ergonomics for training, a reliable .22 platform for recreational shooting, or a carry-training system compatible with existing FN 509 holsters.
