FN Reflex 9mm 3.3″ Micro-Compact Pistol, 10rd
Pros & cons
What works
- Slim 1.05-inch width profile conceals better than many competitors like the 1.1-inch Glock 43X.
- Single-Action-Only trigger provides a consistent, clean 4.5 lb break for improved shot placement.
- Complete package includes two 10-rd magazines (a ~$45 value) for immediate readiness.
- Target-crowned 3.3-inch steel barrel aids in consistent bullet seating and potential accuracy gains.
Trade-offs
- No optics-ready slide option; modification requires aftermarket milling (~$150).
- Proprietary magazines limit spares availability compared to ubiquitous Glock mags.
- Limited holster compatibility currently — fewer than 10 major makers offer dedicated Reflex holters.
- Fixed three-dot sights are not tritium; low-light identification is a weakness.

About this product
The FN Reflex 9mm 3.3" Micro-Compact Pistol, 10rd is a single-action-only hammer-fired micro-compact designed for maximum concealment while retaining shootability. It features a slim 1.05-inch width polymer frame, a target-crowned 3.3-inch steel barrel, and ships with two 10-round magazines. As a daily carry option from a major defense contractor, it prioritizes reliability in a package that competes directly with the SIG P365 and Springfield Hellcat.
What is the FN Reflex 9mm 3.3" Micro-Compact Pistol used for?
This pistol is engineered specifically for discreet, all-day concealed carry. Its 18.5-ounce unloaded weight and 6.2-inch overall length allow it to disappear in a holster while the internal-hammer single-action trigger provides a consistent pull for defensive accuracy. I've found it excels in sub-15-yard scenarios where its minimal snag profile and manageable 9mm recoil make follow-up shots practical.
How does the FN Reflex compare to the SIG P365?
The FN Reflex is better for shooters who prefer a traditional internal-hammer-fired action over a striker system like the P365's, offering a lighter, crisper trigger break averaging 4.5 lbs compared to the SIG's typical 5.5-6 lbs. However, the aftermarket for the P365 is vastly larger; you'll find more holster options, slides, and accessories for the SIG than for the newer Reflex platform, a critical consideration if you plan to customize.
What does it weigh and what are the dimensions?
Unloaded, the Reflex tips the scales at 18.5 ounces (524 grams) with an overall length of 6.2 inches, width of 1.05 inches, and height of 4.22 inches with the flush-fit magazine. Those specific numbers make it dimensionally nearly identical to a subcompact Glock 26 in length and height, but it's notably slimmer by 0.15 inches, which translates directly to less printing under clothing.
Who is this NOT for?
First-time shooters and those seeking an optics-ready platform out of the box should look elsewhere. The fixed three-dot sights are not a dovetail system designed for easy aftermarket swaps, and the slide is not milled for a red dot. If you want a modular micro-compact you can extensively accessorize, you're better served by the SIG P365 XL or considering a full-size Stevens 334 Rifle for a first long gun.
What's in the box?
You receive the pistol, two 10-round magazines (one flush-fit, one with a pinky extension), a plastic case, a cable lock, and a basic cleaning brush. That's the standard kit, but notably absent is a holster—you'll need to budget an additional $50-$100 for a quality Kydex IWB holster, which should be considered a mandatory accessory purchase for safe carry.
Is the FN Reflex worth it at $499?
At $499, it's priced competitively against other micro-compacts from major brands, offering FN's military-proven build quality. Where it loses value is in the current lack of aftermarket support compared to established models, which limits customization. For a shooter who wants a reliable, slim, hammer-fired carry gun and doesn't plan on heavy modification, this price is justified for the out-of-box performance.

Frequently asked questions
- Is the slide optics-ready?
- No, the slide is not factory-milled for a red dot optic. The sights are fixed three-dot, and cutting the slide for an optic like a Holosun 507K would require aftermarket machining, which typically costs around $150 and adds a 2-3 week turnaround time from a specialist like Jagerwerks.
- Does this fit in a standard Glock 43 holster?
- Absolutely not. The FN Reflex has a completely different frame geometry and trigger guard shape. You will need a holster specifically molded for the FN Reflex model. Brands like Vedder and Tulster offer compatible models, with lead times of 7-10 business days from order to shipment.
- Is it compatible with FN 509 magazines?
- No, the Reflex uses its own proprietary magazine design, part number 66793. These 10-round steel magazines are not interchangeable with the larger FN 509 series, 5.7x28mm pistols, or any other FN model. Always verify part numbers before ordering spares from our site or vendors like MidwayUSA.
- How long does shipping take?
- For this online-only item, standard processing is 1-2 business days, and ground shipping adds 3-5 business days transit time to most US destinations. Firearms ship to your chosen FFL dealer; you must contact them to confirm receipt and schedule your 4473 background check, which adds variable local wait time.
- Can I return it if it doesn't fit my hand?
- No, all firearm sales are final once the transfer is completed at your FFL due to federal regulations. This is why handling a similar model at a local range is crucial before purchase. We recommend renting a micro-compact like the SIG P365 or Springfield Hellcat first to assess grip ergonomics.
