FN 509

The pistol that would later be called the FN 509 was originally created by FN as their entry into the XM17 Modular Handgun System (commonly called the MHS trials) trials in 2016. This contract was ultimately awarded to the Sig P320, so FN decided to release a modified version of the X17 pistol (named the 509) to the public in May of 2017.

It’s worth noting that the current FN 509 design being sold to the public isn’t the exact model that was entered into the XM17 trials. FN opted to remove a few of the features that were specific to the military requirements, but not really applicable to law enforcement and civilian use.

The 509 design is based on the popular FNS Compact design with a number of enhancements that would make it eligible for entry into the MHS program. The FN 509 features interchangeable backstraps, ambidextrous magazine and slide releases, front and rear cocking serrations, no less than 4 passive safety mechanisms, and a M1913 picatinny rail.

Currently, the 509 is only available in two 9mm configurations:

  • A 17 round version
  • A 10 round version for magazine restrictive states

As mentioned before, current versions of the FN 509 are not equipped with a manual safety, but the pistol is equipped with 4 passive safety mechanisms. FN has indicated that additional models, including some with a manual safety, will be available at a later date.

The 509 is a striker fired pistol with a double action only (DAO) trigger and currently comes equipped with fixed 3 dot sights. A LEO only version will have fixed 3 dot night sights.

Current versions of the FN 509 are shipping with either two 17 round magazines or two 10 round magazines. While the magazines from the 507 will fit and function in an FNS Compact, the FNS Compact magazines will not fit or work in a 509.

Here are some holster questions that we’ve seen regarding the FN 509 pistol:

Since the FN 509 is built on the FNS Compact pistol platform; will it fit a holster made for an FNS Compact?

While the FN 509 is loosely based on the FNS Compact pistol, the frame on the 509 is different so it won’t fit in a holster made for the FNS Compact. The FN509 requires its own unique holster.

Do you have any leather FN 509 holster options?

Any of the leather models you see listed below are made in a version to fit the FN 509.

A popular gun forum had a post saying that the FN 509 was very close in size to a Glock 19 and would fit in a Glock 19 holster? Is this accurate?

Unfortunately, no it’s not. The FN 509 slide is wider than a Glock 19 slide and the 509 has completely different dimensions, so the 509 won’t fit in a holster molded specific for a Glock 19.

Do you offer an fn 509 holster with light? I have a FN 509 with a TLR-1HL mounted to it?

Any of the holsters listed below for the FN 509 are also available in a version to fit the 509 with a number of the more popular lights (including the TLR-1H) mounted to it. The popular light brands that are supported include:

  • Surefire
  • Streamlight
  • Crimson Trace

I see you have Don Hume holsters listed on some other pages of your web site, but don’t see any Don Hume holsters listed below for the 509?

As it stands right now, Don Hume is not making anything for FN 509 yet.

Can you suggest a good FN 509 IWB holster that will conceal well?

While the FN 509 isn't the smallest pistol for CCW, you can make one work for CCW. We suggest either the MTR Custom Slimline Tuckable or the MTR Custom Adversary IWB.

Any holster listed below is available as an FN 509 holster version.
