Description
FN took an interesting road with the Reflex line, and it pays off in a big way here. Instead of the striker-fired setup you see on nearly every other micro-compact, the Reflex XL MRD runs an internal hammer. What that means at the range is a lighter, crisper single-action trigger that breaks around 5 pounds, plus a slide that racks with noticeably less effort than most guns this size. If you or someone in your household struggles with stiff slides, this pistol is worth a serious look.
A Reflex XL Built to Shoot, Not Just Carry
The XL grew in the right places. A 3.8 inch cold hammer-forged stainless barrel with a recessed target crown stretches the sight radius to 5.55 inches, and the longer grip fills the hand instead of leaving your pinky dangling. FN reworked the ergonomics too, adding a palm swell, an undercut trigger guard, an extended beavertail, and interchangeable backstraps so you can dial in the fit. At 20 ounces and just over an inch wide, it still disappears under a t-shirt. This version ships with two 10-round magazines for 10+1 on board.
Optics Ready with Sights You Can Trust
The MRD slide is cut for micro red dots sharing the Shield RMSc or Holosun 507K footprints, which covers most of the popular carry optics out there. Until you mount one, the factory sights carry their weight: a tritium front with a high-visibility orange ring paired with a blacked-out U-notch rear that keeps your eye where it belongs in any light. Front and rear slide serrations give you plenty of grip for press checks and reloads.
Everyday Details on the Reflex XL MRD
This NMS model skips the external thumb safety in favor of multiple internal passive safeties, keeping the draw simple. A reversible magazine release accommodates lefties, and the accessory rail accepts compact lights like the Streamlight TLR-7 Sub and SureFire XSC. It is a well-rounded carry pistol from a company that has been building serious firearms for well over a century, and it shows in the details.

Frequently Asked Questions
What red dot optics fit the FN Reflex XL MRD?
The MRD slide cut accepts micro red dots built on the Shield RMSc or Holosun 507K footprints. That covers a big chunk of the popular carry optics on the market, including the Holosun 507K, EPS Carry, Shield RMSc, and similar footprint sights. No adapter plate is needed for optics in those footprints.
How is the Reflex XL different from the standard FN Reflex?
The XL adds a 3.8 inch barrel versus the standard 3.3 inch, along with a taller grip, longer sight radius, and updated ergonomics like a palm swell, extended beavertail, and interchangeable backstraps. It runs about 20 ounces compared to 18.4 on the original. The trade is a touch more size for a noticeably easier gun to shoot well.
Does the FN Reflex XL MRD have a manual safety?
This NMS version does not have an external thumb safety, which many folks prefer for a carry gun since it keeps the draw simple. It still incorporates multiple internal passive safeties, so the internal hammer-fired design remains drop safe and secure in a proper holster.
Is the slide really easier to rack than other micro compacts?
Yes, and it comes down to the internal hammer design. Because the action does not rely on heavy striker spring tension, the slide takes less force to manipulate than most striker-fired micros. Combined with the front and rear serrations, it is one of the easier small 9mm pistols to run, which matters for shooters with limited hand strength.
