The New FN 509 Compact Tactical Pistol

FN America has a new compact 9mm on the market that they say is the smallest, most concealable 9mm tactical pistol available. The pistol ships with three magazines, with one each of the 12, 15, and 24-round magazines. Those who live in states with higher restrictions can get a set of three 10-round magazines. So, altogether that’s 51-round capacity when you’re carrying all three mags. We can’t help wonder how concealable it is with the 24-round mag, though.

There is some discussion floating around about where to find a suitable holster for this compact pistol. Some report having luck with Odin Holsters by checking out with a 509 Tactical with a notation that it’s for a 509c. Others suggest Garrett Holsters or Muddy River Tactical.

According to the company, the FN 509 Compact Tactical is the smallest and most concealable 9mm tactical pistol available on the market.

Here’s the info, per the official press release:

The FN 509 Compact Tactical, available in both black and FN-signature flat dark earth (FDE), can be easily deployed as an everyday carry with the standard 12- or 15-round magazines or on the range with the extended 24-round magazine, giving 51 rounds of ammunition at the ready.

The 4.3-inch cold hammer-forged threaded barrel makes it compatible with today’s most popular aftermarket accessories like compensators or suppressors and the FN Low-Profile Optics-Mounting System,™ capable of accepting more than 10 miniature red sights, rounds out this compact tactical pistol.

The compact frame features the FN 509-signature enhanced grip texturing for secure hold, a MIL-STD 1913 picatinny rail that is compatible with most compact pistol lights and interchangeable backstraps for a customized fit.

Additional features like the suppressor-height night sights aid in co-witness of the miniature red dot and while the optics system is not in use, the protective slide cap provides a serrated surface for racking the slide from any surface and ensures iron sight alignment.

The FN 509 Compact Tactical is available in Black and FDE.

FN advises that the 509 Compact Tactical ships in a soft sided case with the optics mounting kit and the three magazines. That’s 12, 15, and 24-round mags or for restrictive states, three 10-round magazines.
