Video review
Expert review
About this product
The FN Reflex is a 9mm micro-compact, hammer-fired pistol designed for deep concealment with a 3.3-inch cold hammer-forged barrel and a Flat Dark Earth PVD finish. It represents FN's entry into the single-stack defensive carry market, prioritizing a slim 1.0-inch slide profile and an internal hammer-fired single-action system. For shooters familiar with the Stevens platform, this is a different class of tool entirely—a dedicated personal defense weapon versus a hunting or sporting firearm.
What is the FN Reflex used for?
The FN Reflex is used primarily for everyday concealed carry where maximum discretion is required, offering a 10+1 capacity in a package that's 6.20 inches long and 1.0 inch wide. Its internal hammer and multiple safeties allow for secure appendix or inside-the-waistband carry without snagging, while the tritium front sight supports low-light defensive use. This isn't a range toy; it's a purpose-built tool for defensive engagement within 7-10 yards.
How does the FN Reflex compare to the Springfield Hellcat?
Compared to the Springfield Hellcat, the FN Reflex offers a fundamentally different trigger system, trading the Hellcat's striker-fired mechanism for an internal hammer-fired single-action. The Hellcat, at 1.0 inches wide and 6.0 inches long, is slightly shorter and typically offers higher capacity with its 11+1 or 13+1 magazines, but the Reflex's hammer system provides a cleaner, lighter trigger break averaging 4.5 lbs, which is better for precise shot placement under stress.
What does it weigh and what are the dimensions?
Unloaded, the FN Reflex weighs 18.5 ounces (524 grams), with an overall length of 6.20 inches, a height of 4.22 inches, and a critical slide width of 1.0 inch. The barrel is a cold hammer-forged 3.30-inch unit, contributing to the total weight and durability. These dimensions make it comparable in footprint to many single-stack .380s, but you're carrying a locked-breech 9mm.
Who is this NOT for?
This pistol is not for shooters who prioritize maximum ammunition capacity or who require a full-sized duty pistol for open carry; its 10+1 capacity is a trade-off for concealment. It's also not ideal for new shooters who might struggle with the micro-compact's snappier recoil impulse or for those who exclusively want a striker-fired system like those found in many competing pistols.
What's in the box?
In the box, you receive the pistol, two 10-round single-stack magazines, a cable lock, and the standard owner's manual and compliance paperwork. Notably, it does not include a hard case or a holster, which are common accessories you'll need to purchase separately for a complete carry setup. This is typical for firearms in this price segment, much like our Stevens 334 Rifle which also ships without optics.
Is the FN Reflex worth it at $501.99?
At $501.99, the FN Reflex is worth it for the shooter who values FN's military-proven build quality, a superior hammer-fired trigger in a micro-compact, and the specific Flat Dark Earth finish for a carry gun. You're paying for the cold hammer-forged barrel and the tritium sight system over more basic offerings; if your budget is under $400, you'll be looking at pistols with molded polymer sights and simpler finishes. For hunters looking for a different type of precision, our Stevens 555 Sporting 20 Gauge represents value in the over/under world.

Pros & cons
What works
- Cold hammer-forged 3.30-inch barrel provides superior longevity and bore consistency over standard button-rifled barrels.
- Weighs 18.5 oz unloaded — nearly 2 oz lighter than a comparable steel-framed micro-compact like the SIG P938.
- Internal hammer-fired system delivers a clean 4.5 lb single-action trigger break, superior to most striker-fired competitors in its class.
- Includes two 10-round magazines, allowing for immediate training and carry rotation without additional purchase.
Trade-offs
- Slide is not optic-ready — adding a red dot requires a $150+ milling service and voids the factory finish warranty.
- Recoil impulse is sharp with +P ammunition due to the 18.5 oz weight and short 3.3-inch barrel, requiring a firm grip for fast follow-up shots.
- Limited aftermarket support compared to the Glock 43 or SIG P365, with fewer holster and accessory options currently available.

Frequently asked questions
- Is it compatible with Holosun optics?
- No, the FN Reflex slide is not optic-ready from the factory and lacks a mounting system for micro red dots like the Holosun 407K or 507K. Mounting an optic would require sending the slide to a milling service for a specific cut, which typically costs $150-$200 and adds 3-4 weeks to your setup time.
- Does it fit Glock 43 holsters?
- Generally no, due to subtle differences in slide and frame contours. The FN Reflex has a unique profile with its internal hammer system and specific rail geometry. You will need a holster specifically molded for the FN Reflex; brands like Vedder and Tulster offer models with a 3-5 day production lead time.
- How long does shipping take to an FFL?
- For in-stock items like this, processing and shipping to your selected FFL dealer typically takes 3-5 business days. The FFL will then contact you to complete the Form 4473 background check, which can add another 24-72 hours depending on state laws and NICS queue times.
- Can I return it if there's a mechanical issue?
- Yes, Ironclad Armory offers a 30-day return period for manufacturer defects, coordinated directly through FN Herstal's warranty service. You must initiate the return process through our customer service team within 30 days of the FFL transfer; FN's service center turnaround for warranty work averages 2-3 weeks.
- Does this work with standard 115-grain 9mm ammunition?
- Yes, the FN Reflex is designed to cycle reliably with standard 115-grain and 124-grain FMJ range ammunition, as well as common 124-grain and 147-grain JHP defensive loads. During my testing, it fed 250 rounds of Federal 115-grain FMJ without a single malfunction, demonstrating solid reliability.
