Just a couple of weeks ago, I got my hands on a member of the FN 509 family of weapons, the Compact MRD (Modular Red Dot) model. I had overlooked the newest of the FN models, and that was an absolute mistake. The 509 Compact MRD might be a dark horse contender, but one worthy of betting the farm on when it comes to performance. This week, I am going to give you five good reasons to carry the 509 Compact MRD.
1. FN’s Reputation
FN has the motto, “The World’s Most Battle Proven Firearms,” and that isn’t a statement without merit. Between the M2, Browning High Power, FAL, SCAR, M240, M249, and M-16/M-4 production by FN, it’s hard to argue they aren’t correct.
But on the handgun side, while the 509 series is new, it also has a heritage with a proven track record. The FNX-45 Tactical is still a hard one to beat in the battlefield sidearm department, and the 509 series is a direct descendant.
During testing it had not one hiccup, and I shot it more than I should have. This gun is so much fun, and so easy to run fast, that it is hard to stop loading magazines. Highly recommend you order a case of 9mm when you order your 509 (see review video embedded below).
The 509 Compact MRD can fill a variety of roles, everything from a primary carry gun to a backup duty pistol. This is largely due to the magazine size one opts to use because depending on the choice it can feel like two different guns.
With a 12-round magazine inserted, you have a grip and profile like most other compact guns in class: Glock 19, M&P Compact, etc. But with the 15-round magazine inserted you don’t just get more bullets. The configuration smoothly extends the grip profile as well. Which makes it the equal to what I call hybrid size guns, or polymer “Commanders,” like the Glock 19X and SIG P320 X-Carry.
For that reason, I usually carry mine with the 15 round magazine inserted, and the 12 as a reload (If I opt to carry a reload). That is a bit backward from the norm, but it puts most of my bullets upfront if the party starts. And as soon as my spare 15s arrive, I will carry them exclusively.
3. Red Dot Ready
You may not be ready to carry a red dot just yet, but the future is coming. Also, just like mine, your eyes aren’t getting any younger. In this day and age, it is really nice to be able to buy a gun that can be equipped with red dots if you like. And the 509 Compact MRD does just that. With a patented red dot mounting system that also gives it a best-in-class depth of mount, the 509 Compact MRD is a perfect choice.
Included in the box are adaptors for 10 popular red dots. I paired it with the Leupold Delta Point Pro because it is has a reputation as being incredibly durable. The Delta Point dominates the competition market, so you know it is going to survive normal concealed carry use. It also features motion-sensing auto on/off and efficient circuitry to extend battery life.
The 509 Compact MRD really blew my doors off during review time because of how well it shot. Compared to the competition it is absolutely among the best and is remarkably smooth for a striker-fired gun. That, coupled with the unique grip texturing, had me hammering targets with the 509 like it was an old friend. On the first magazine!
This is a trigger you need to feel at the gun counter (or preferably the range) to truly appreciate. On paper, it is the same weight as many others, 5.5 pounds. But the geometry of the pull and design of the trigger shoe make it feel like much less. Just a dry fire or two, and you will see exactly what I mean.
5. Market Support
With an all-new gun usually you will have to wait a while on accessories. But since the 509 Compact MRD comes from the already popular 509 series, and FN is a massive manufacturing force, “stuff” is already available.
Most important for a concealed carry, holsters are available. And in plentiful supply. I counted a dozen in a quick search, including this one from PHLster. PHLster has a reputation for innovative CCW platforms, as well as comfort. These guys actually carry things and think about it, not just smash Kydex together. With the PHLster, the 509 disappears into your waistband. Definitely recommend it.
Magazines, parts, night sights — everything is already available. Which means you can customize to your needs, always a bonus.
In the highly competitive compact handgun market, it is rare to see a real contender to the crown. But the 509 Compact MRD is just that. Small enough to conceal, but still big enough to shoot. With the crisp trigger and optional grip length, the 509 Compact MRD surges to the head of the pack.
