Description
FN took a different road with the Reflex, and it shows the moment you press the trigger. Instead of the striker-fired setup found on nearly every other micro 9mm on the market, FN tucked a tiny internal hammer inside this pistol, giving it a single-action trigger pull that breaks clean somewhere in the 4.5 to 5.5 pound range. That hammer-fired design does double duty too, since it also lightens up the effort needed to rack the slide, which matters a lot on a gun this small.
The 3.3 inch barrel is cold hammer-forged and target-crowned, with a polished chamber and feed ramp that FN carries over from its full-size 509 line. Overall the pistol runs 6.2 inches long, 4.27 inches tall, and just 1 inch wide at the slide, tipping the scale at 18.4 ounces unloaded. That kind of size puts it right in the same conversation as the P365 and Hellcat, but the grip texture and hand-filling stippling give it a more locked-in feel than a lot of its rivals.
FN Reflex Sights and Controls
Up top you get steel dovetail sights rather than plastic, with a tritium front insert wrapped in a high-visibility orange ring and a two-dot rear that's drift adjustable for windage. The magazine release is reversible for lefties, and takedown is done through a dedicated lever on the frame that rotates a quarter turn, meaning you never have to pull the trigger just to clean the gun.
Capacity Built Into the FN Reflex
Two magazines ride along in the box, an 11 round flush-fit mag with a pinky extension floorplate for a fuller grip, and a 15 round extended mag that stretches the frame out for a full firing grip. Run them together and you're carrying 26 rounds plus one in the pipe, which is a lot of firepower to tuck into a gun this thin.
Carry Ready Features on the Reflex
A short accessory rail sits under the dustcover, sized to work with micro compact lights like the Streamlight TLR-7 sub and SureFire XSC rather than full duty-size lights. Between the slim profile, the rounded edges, and a slide that's genuinely easier to rack than most guns in its class, this is a pistol built from the ground up for all day carry rather than a shrunk-down duty gun.

Frequently Asked Questions
Is the FN Reflex striker-fired like most other micro 9mm pistols?
No, and that's actually the standout feature here. The Reflex uses an internal hammer instead of a striker, which is part of why the trigger pull feels so clean compared to most guns in this size class. It also means slide manipulation takes noticeably less effort.
Does the FN Reflex 3.3in have a manual safety?
This particular model is the non-manual safety configuration, relying on FN's internal passive safeties including a firing pin block and trigger safety. FN does also produce a manual safety version if you prefer a thumb lever, but this listing is the NMS setup.
What is the total round capacity with both magazines?
You get an 11-round flush-fit magazine and a 15-round extended magazine in the box, so between the two you have 26 rounds on tap plus one in the chamber. Most owners carry the 15-rounder in the gun and keep the 11-round mag as a spare, or vice versa depending on how deep they need to conceal.
Can I mount a weapon light on the FN Reflex?
Yes, there's a short accessory rail under the dustcover, but it's sized for micro compact lights rather than full-size ones. The Streamlight TLR-7 sub and SureFire XSC are the two lights most commonly recommended for this rail.
Is this version of the Reflex optics ready?
This is the standard iron-sighted model rather than the MRD optics-ready variant, so it comes with a solid top slide and no cut for a red dot. If you want a direct-mount optics cut for something like a Holosun 507k or Shield RMSc, look for the Reflex MRD instead.
How does the trigger on the FN Reflex compare to guns like the P365 or Hellcat?
Because it's hammer-fired rather than striker-fired, the Reflex tends to break cleaner and lighter than most of its striker-fired competitors, with a lot of owners and reviewers pointing to the trigger as the reason they picked it over the usual micro 9 suspects. Reset is a touch longer than what you'd feel on a Glock-style striker gun, but the tradeoff for a crisper break is one most people are happy to make.
