About this product
The FN 502 Tactical .22 LR 4.6in FDE Optics-Ready is a compact, semi-auto pistol built for high-round-count training and economical range work. It combines a threaded steel barrel, optics-ready slide, and FN-style ergonomics in a Flat Dark Earth frame. This is a shooter's tool for getting reps in without burning through centerfire ammo budgets.

Key Features
- Optics-Ready Slide – Accepts multiple micro dot footprints and ships with a removable cover plate. Why it matters: you can mount your preferred red dot without adapter plates, cutting setup time and keeping cowitness with the suppressor-height fixed sights.
- Threaded 4.6-Inch Barrel – Factory-threaded barrel lets you attach a suppressor or compensator. Why it matters: shoot suppressed for less noise and reduced recoil, or run a comp for flatter follow-up shots in .22 LR.
- Ambidextrous Controls – Slide stop and manual thumb safety are reversible for left or right hand. Why it matters: no fumbling with controls during drills—works for shooters of any handedness or support-hand shooting.
- Single-Action Hammer System – Crisp, consistent trigger pull with a short reset. Why it matters: replicates the trigger feel of full-size service pistols, making training transferable to your carry gun.
- FN-Style Ergonomic Grip – Textured polymer frame with finger grooves and a high undercut. Why it matters: natural point-of-aim and secure grip under recoil, even with sweaty hands or gloves.
Who It's For
This pistol is for shooters who want a .22 LR trainer that mirrors the handling of a full-size duty gun. It's ideal for high-volume range sessions, new shooters building fundamentals, and anyone who wants to shoot suppressed on a budget. If you already carry an FN or run a red dot on your centerfire pistol, this keeps the muscle memory consistent.
Pros & Cons
- Pro: Optics-ready out of the box with broad footprint compatibility—no need for aftermarket milling.
- Pro: Threaded barrel included, saving you $100+ compared to buying a separate barrel.
- Con: The single-action hammer system means no second-strike capability; if a round fails to fire, you must manually rack the slide to reset.

FAQ
Does the FN 502 Tactical come with a threaded barrel?
Yes. The 4.6-inch barrel is factory-threaded (1/2x28 TPI) and includes a thread protector. You can mount a suppressor or compensator right out of the box.
What optics fit the FN 502 Tactical slide?
The slide is cut for multiple footprints: RMRcc, Shield RMS/RMSc, Docter/Noblex, C-More STS, and DeltaPoint Pro. It ships with adapter plates for most of these. The suppressor-height front and rear sights co-witness with most micro red dots.
Is the FN 502 Tactical reliable with all .22 LR ammo?
Per FN America specs, the pistol is designed for high-velocity .22 LR ammunition. Standard-velocity or subsonic loads may not cycle reliably in all conditions. Stick with 1200+ fps rounds for best function.
Can left-handed shooters use the safety and slide stop?
Yes. The thumb safety and slide stop are ambidextrous from the factory. No modifications needed for left-hand operation.
What is the magazine capacity?
The FN 502 Tactical ships with two 15-round magazines. Aftermarket 10-round magazines are available for restricted states.
