Description
FN entered the micro-compact 9mm market in 2023 with the Reflex, and it didn't take long for carry-focused shooters to take notice. The gun measures just one inch wide at the slide, which makes a real difference after a few hours on the waistband. At 18.4 ounces unloaded and 6.2 inches overall, it checks every box for deep concealment without giving up the refined engineering FN is known for. The polymer frame wears in-mold stippling that actually grips under pressure, and the reversible magazine release means left-handed carriers aren't left out.
What Makes the FN Reflex Trigger Different
The single biggest thing that separates the Reflex from most of its competition is the internal hammer-fired SAO system. Where most micro-compacts rely on striker-fired designs that often result in a spongy or inconsistent trigger, the Reflex uses a concealed internal hammer to deliver a clean, crisp break in the 4.5 to 5.5 pound range. There's no external hammer to snag on clothing, but you still get the trigger quality benefit that hammer-fired pistols are known for. Disassembly also doesn't require a trigger pull, which is a practical safety advantage worth mentioning.
FN Reflex Sights and Barrel Quality
This model ships with steel dovetail-mounted three-dot night sights: a tritium front insert surrounded by a high-visibility orange circle, paired with a double-dot rear. Low-light target acquisition is noticeably faster with that front sight setup compared to plain white dots. The 3.3-inch barrel is cold hammer-forged with a recessed target crown and a polished chamber and feed ramp, which contributes to both long-term accuracy and reliable feeding across a wide range of 9mm loads. The barrel's 1:10 right-hand twist rate is well-suited for standard defensive ammunition weights.
The frame also includes a slimline accessory rail sized for subcompact lights like the Streamlight TLR-7 Sub GL and SureFire XSC, so there's a path to a weapon-mounted light if your carry setup calls for it. The front and rear slide serrations are deep and usable, and the slide racking force is notably light for the platform, which matters for anyone with reduced hand strength. This 10-round version is the right choice where flush-fit carry capacity is the priority.

Frequently Asked Questions
How does the FN Reflex trigger compare to other micro-compact pistols?
The Reflex uses an internal hammer-fired single-action-only system rather than the striker-fired mechanisms found in most of its competitors. This setup produces a cleaner, more consistent break in the 4.5 to 5.5 pound range with minimal overtravel. For a gun this size, the trigger quality is genuinely a standout feature and one of the main reasons people choose it over similar options.
What weapon lights are compatible with the FN Reflex?
The Reflex uses a non-proprietary slimline accessory rail that is sized for subcompact lights, not full-size ones. FN confirms compatibility with the SureFire XSC and the Streamlight TLR-7 Sub (Glock version). Standard 1913 Picatinny lights won't fit the slimline rail, so make sure to check compatibility before purchasing a light.
Does the FN Reflex require a trigger pull to disassemble?
No, and that's actually one of the practical advantages of the internal hammer design. Field stripping the Reflex only requires locking the slide back and flipping the takedown lever, with no trigger pull needed. This is a meaningful safety improvement over many striker-fired pistols in the same category.
What is the difference between this 10-round model and the standard FN Reflex?
This specific model (MPN 66-101412) ships with two 10-round flush-fit magazines instead of the 11-round and 15-round magazines included with other Reflex configurations. The pistol itself is mechanically identical, so it will also accept 11- and 15-round FN Reflex magazines if you want to run higher capacity later. The 10-round version is specifically designed for those who need a flush-fit profile.
Are there dedicated holsters available for the FN Reflex?
Yes, holster availability for the Reflex has grown significantly since its 2023 launch. Companies like ANR Design, Vedder Holsters, Odin Holsters, and others produce Kydex IWB and AIWB options purpose-built for the Reflex. If you plan to run a weapon light, make sure the holster is specifically cut for your light model, since the slimline rail uses a non-standard footprint.
What kind of sights does this FN Reflex model have?
This model comes equipped with steel dovetail-mounted night sights featuring a tritium front insert surrounded by a high-visibility orange circle, and a double-dot rear sight. The orange circle on the front sight helps the eye pick it up quickly in low light without relying solely on the tritium glow. Sight radius measures 5.05 inches.
