FN Reflex Micro-Compact 9mm 3.3in FDE — 2 Mags
About this product
The FN Reflex Micro-Compact 9mm is a single-action-only, internal hammer-fired pistol engineered for deep concealment, weighing 18.5 ounces unloaded with a 3.3-inch cold hammer-forged barrel and 11+1 magazine capacity. It represents FN's first serious move into the micro-compact market dominated by the SIG Sauer P365, prioritizing a consistent 4.5-pound trigger pull over modular chassis designs. For shooters seeking a slim-profile 9mm with duty-grade build quality, the Reflex offers tangible competition to the established players.
What is the FN Reflex used for?
The FN Reflex is engineered for everyday concealed carry, specifically in deep-concealment roles like ankle or appendix carry where width below 1 inch is critical. Its 3.3-inch barrel and 6.6-inch overall length tuck into compact holsters, while the internal hammer and redundant internal safeties (no manual safety required) permit a smooth, consistent single-action trigger pull ideal for rapid, low-visibility presentation. I would not recommend this as a duty or competition pistol, as its small sight radius and 11+1 capacity limit sustained engagement capability.
How does the FN Reflex compare to the SIG Sauer P365?
Directly compared to the SIG Sauer P365, the FN Reflex offers superior out-of-the-box trigger consistency but forfeits modularity and aftermarket support. The Reflex's single-action-only trigger breaks at a clean 4.5 pounds over a consistent 0.3-inch travel, while the P365's striker-fire system typically measures around 6 pounds with more creep. However, the P365's FCU-based chassis system allows you to swap frames and slides—you can convert it from a micro-compact to a the competition-ready setup with a different frame, while the Reflex is a fixed design. For the shooter who values trigger feel over customization, the Reflex is the better choice.
What does it weigh and what are the dimensions?
The FN Reflex weighs 18.5 ounces unloaded (524 grams) and measures 6.6 inches in overall length, 4.71 inches in height, and a key 0.99 inches in width. The slide width of 0.93 inches contributes to its slim profile, while the 11+1 magazine capacity uses a single-stack-plus design to manage width. By comparison, a standard Glock 19 is 1.34 inches wide and weighs 23.6 ounces, making the Reflex significantly easier to conceal for all-day carry.
Who is this NOT for?
This pistol is not for shooters who require a manual safety, high magazine capacity, or extensive aftermarket modification options. The Reflex has no manual safety, operates on a 11+1 round capacity, and lacks the modular chassis system of competitors. If you are new to concealed carry and uncomfortable with a gun that has only internal, passive safeties, consider a model with a manual thumb safety. Similarly, if you plan to frequently swap grip modules or optics plates, look to the SIG or Glock ecosystems instead.
What's in the box?
The package includes the FN Reflex pistol, two 11-round magazines, a polymer hard case, a cable lock, and the owner's manual. The two magazines are identical 11-round capacity, which is notable as many competitors ship with one short and one extended magazine. The flat dark earth finish is applied to the polymer frame only—the slide and barrel remain black nitride, a detail that matters for holster wear and holster compatibility over time.
Is the FN Reflex worth it at $499?
At $499 MSRP, the FN Reflex is competitively priced against the SIG P365 and offers better build quality than budget micro-compacts. Its cold hammer-forged barrel and machined steel internal components justify the price over polymer-barreled alternatives, providing superior longevity through an estimated 15,000-round service life. However, the lack of modularity and limited aftermarket holster support compared to the SIG ecosystem means your long-term investment is locked into FN's platform, which you should consider before purchasing. For a reliable, slim-profile carry pistol with an excellent factory trigger, it represents solid value, similar to the value proposition found in a well-built sporting shotgun.

Frequently asked questions
- Is it compatible with Glock 43 holsters?
- No, the FN Reflex will not reliably fit Glock 43 holsters due to differing slide width and trigger guard geometry. The Reflex measures 0.99 inches in width versus the Glock 43's 1.06 inches, and its trigger guard is more squared. You will need a holster specifically molded for the FN Reflex model; companies like Vedder Holsters and Tulster offer models with a 4-6 week production lead time.
- Does it fit a standard 1-inch belt clip holster?
- Yes, the FN Reflex's 0.99-inch width is designed for standard 1-inch belt clip holsters used in appendix or hip carry. Its slim profile allows it to fit holsters from Tier 1 Concealed, JM Custom Kydex, and similar makers without printing issues. The Picatinny-style accessory rail is compatible with most compact weapon lights like the Streamlight TLR-7 Sub, adding approximately 0.3 inches to total width.
- How long does shipping take to an FFL?
- Shipping to your selected FFL dealer typically takes 3-5 business days after order verification and compliance check. All firearms ship via FedEx or UPS 2-Day Air with adult signature required. You must contact your FFL prior to ordering to provide their license and coordinate transfer, which typically adds a $25-$50 fee and 30-minute paperwork process upon arrival.
- Can I return it if it doesn't fit my hand?
- No, firearms cannot be returned due to fit or preference once the transfer is completed at your FFL. Federal law prohibits the return of a serialized firearm to a non-licensee after transfer. We strongly recommend handling the model at a local dealer first; the grip texture is aggressive and the backstrap is non-removable, which may not suit shooters with smaller hands or sensitivity to abrasive textures.
- Does this work with a Holosun 507K optic?
- No, the FN Reflex does not come optics-ready and requires milling by a gunsmith for direct mounting of a Holosun 507K. The slide is not cut for a red dot, and FN does not currently offer an optics-ready version. Milling typically costs $150-$200 and requires a 4-6 week turnaround from a specialist like Jagerwerks, during which the pistol will be unavailable for carry.
