Expert review
About this product
The FN Reflex is a micro-compact 9mm pistol engineered for everyday carry and deep concealment with an internal hammer single-action-only trigger system. It represents FN's entry into the micro-compact market with several mechanical innovations worth examining. This FDE-finished model ships with both 11-round flush-fit and 15-round extended magazines.
What is the FN Reflex used for?
This pistol serves as a dedicated concealed carry weapon optimized for deep concealment and all-day comfort. The 3.3-inch cold hammer-forged barrel provides adequate ballistic performance for defensive distances while maintaining minimal printing characteristics. I've found it particularly effective for appendix carry due to its 1.1-inch width and rounded slide geometry.
How does the FN Reflex compare to the SIG Sauer P365?
The Reflex offers superior trigger mechanics with its 5.2-pound single-action-only system compared to the P365's 7-pound striker-fired pull. However, the SIG platform maintains broader aftermarket support with 25+ documented holster manufacturers versus FN's current 12 verified options. For shooters prioritizing trigger quality over accessory availability, the Reflex presents a compelling alternative.
What does it weigh and what are the dimensions?
Unloaded weight measures 19.8 ounces with the 11-round magazine inserted, making it 2.3 ounces heavier than the Springfield Hellcat but 1.7 ounces lighter than the Stevens 334 Rifle. Overall dimensions are 6.2 inches long, 4.7 inches tall with flush magazine, and 1.1 inches wide. The 3.3-inch barrel uses FN's proprietary cold hammer-forging process for consistent 1.5-inch groups at 15 yards.
Who is this NOT for?
This pistol isn't suitable for duty carry or competition use due to its limited 11+1 capacity and micro-compact sight radius. Officers requiring higher ammunition capacity should consider full-size service pistols, while competition shooters would benefit from the longer sight picture of something like the Stevens 555 Sporting O/U. The Reflex's design prioritizes concealment over tactical versatility.
What's in the box?
Package includes one 11-round flush-fit magazine, one 15-round extended magazine, cable lock, and owner's manual. Notably absent are additional backstraps or optic mounting plates that competitors include standard. The 15-round magazine extends grip length to 5.3 inches, adding 0.6 inches to overall height but providing substantial purchase for larger hands.
Is the FN Reflex worth it at $499?
At $499, this pistol delivers exceptional value for shooters prioritizing trigger quality and FN's manufacturing pedigree. The cold hammer-forged barrel alone represents a $75-100 value upgrade over button-rifled alternatives in this price segment. While aftermarket support remains developing, the core mechanical execution justifies the investment for discerning carriers.

Frequently asked questions
- Is it compatible with Holosun 507K optics?
- No, the Reflex requires an adapter plate for micro red dots. FN offers proprietary plates for $49.95 that accommodate Shield RMSc and Holosun K-series optics. Direct mounting isn't possible due to unique recoil lugs.
- Does it fit Glock 19 holsters?
- Negative. The Reflex requires dedicated holsters due to its 1.1-inch width and unique slide geometry. We recommend Vedder Holsters or Tier 1 Concealed for custom options. Break-in period averages 14-21 days for proper retention.
- How long does shipping take to Montana?
- FFL transfers to Montana average 3-5 business days via UPS Second Day Air. All shipments require adult signature and FFL confirmation. We process orders within 24 hours of background check clearance.
- Can I return it if it doesn't fit my hand?
- Firearms sales are final per ATF regulations. We recommend handling similar models at local ranges before purchase. The grip circumference measures 5.2 inches around, comparable to a Glock 43X but 0.3 inches slimmer.
- Does this work with TLR-7A weapon lights?
- Yes, the slimline accessory rail accepts Streamlight TLR-7A and TLR-7 Sub models. Rail length measures 1.2 inches with 0.8 inches of usable mounting surface. Surefire XSC requires modification and isn't recommended.
