What to Know Before Buying a FN Herstal FNS 9mm

Though FN Herstal is an international firearms manufacturer, they have operations in the U.S. as well.

So, firearms purchased from FN America will be compliant with all U.S. firearms regulations. As long as you purchase a firearm from FN America, you shouldn’t have to worry. But, if you purchase a second-hand pistol, make sure it is stamped with “Made in USA” on the barrel.

The FNS™ -9 comes with a trigger safety. Some shooters don’t like this type of safety. And if you want even more security, you can get one with a manual safety, too.

As for warranty, FN America doesn’t offer a written warranty, per se, because of government regulations requiring a “limited” warranty on firearms. But, they do have a service and repair policy.

Features and Benefits of FN Herstal FNS 9mm

The FNS™ -9 is loaded with features to benefit a range of shooters, from personal defense to law enforcement and military personnel. Let’s look at some of these features so you’ll gain a better understanding of them.

Striker Fired

Rather than being hammer-fired, the FNS™ -9 is a striker fired pistol. When the slide is racked to load a round into the chamber, the internal striker is also cocked. The only way to de-cock the striker is to pull the trigger (never do this with a round in the chamber unless you’re at the range!).

Glocks, Barettas, and the Springfield XD are other examples of striker fired handguns, though, for the most part, these pistols come with a higher price tag.


All models of this 9mm come with a trigger safety, which engages when you put tension on the trigger.

It’s also available with an additional manual thumb safety, a switch located on the back of the slide. This combination gives you two means of security, which is perfect if you have a family.

For law enforcement or personal protection, you’ll want to practice drawing and releasing the safety so you develop muscle memory. That way, in a situation where you have only a second or two to react, your body will flip off the safety as you draw.

On models with a manual safety, the thumb switch is ambidextrous, so it can easily be operated by either right- or left-handed shooters.

Polymer Frame with Rail

The FNS™ -9 comes with a molded polymer frame with accessory rail. The polymer makes for a durable, shock-proof frame with a checkered pattern for a secure grip. The MIL-STD 1913 accessory rail allows you to add a tactical light or laser sight with ease.

This type of frame is excellent for law enforcement or security use because it stands up to repeated holstering and is durable enough for daily care, even getting smacked around when you jump in and out of a vehicle.

Loaded Chamber Indicator

This 9mm also comes with an external extractor and a loaded chamber indicator. This enables you to see at a glance that there is no round inside the chamber.

However, this does not mean that you should ignore firearms rule #1: Assume all firearms are loaded until you check them. Always follow proper firearm safety even with a loaded chamber indicator.

Ambidextrous Magazine Release and Slide Stop

This handgun has ambidextrous buttons for the magazine release and slide stop. This makes it easier for left-handed shooters to operate.

The magazine release is positioned so it shouldn’t interfere with the average shooting grip. But, if you have large hands, you might want to examine your grip to ensure you won’t drop the mag when shooting.

Polished Feed Ramp and Chamber

I first saw this on a Taurus 24/7, and a polished feed ramp makes a difference in smooth round feeding.

I never had a misfeed on the Taurus and was highly pleased with the performance of the firearm. Since then, I’ve seen many manufacturers offering a polished feed ramp in their semi-automatic pistols.

Interchangeable Backstraps

FNH ships this 9mm pistol with two interchangeable backstraps. This makes it easy to customize the firearm for your grip.

You should be able to achieve the perfect grip with one of these backstraps. They also come with eyelets to attach a lanyard to.

Magazine Capacity

This pistol ships with 3, yes, that’s 3 magazines in either 10- or 17-round capacities. For those in law enforcement or security occupations, a 17-round magazine can be a lifesaver.

Even though some may claim 17 rounds is overkill in personal defense situations, you can still choose to use the higher capacity magazine.


Besides the 3 magazines and 2 backstraps, you’ll also receive your 9mm with a locking mechanism, a fired cartridge, and a fitted polymer case that you can also lock. Plus, you’ll get an owner’s manual.

Special Pricing

FNH offers special pricing for law enforcement or military personnel. You can request special pricing by emailing FN America at [email protected].

However, this is a relatively inexpensive firearm even if you don’t qualify for the special pricing.


FN America, like many firearms manufacturers, doesn’t offer a written warranty because of Federal regulations about the wording of warranties regarding firearms.

But, that doesn’t mean they don’t have a policy in place to cover services or repairs. They do have a page on their website dedicated to service and repairs.
