FN Herstal FN FNX-40

The FNX-40 is a double action/single action handgun with an ergonomic polymer frame and low bore axis for reduced felt recoil and improved control. The grip panels are checkered and ribbed for comfortable no-snag carry, and the gun comes with four interchangeable backstrap inserts to quickly adapt to your hand size. The slide is made of profiled stainless steel and has cocking serrations front and rear, while the barrel is 4 inches of hammer-forged stainless steel. Ambidextrous operating controls make the FNX-40 usable for both right- and left-handed shooters.

I have been a fan of FN Herstal for years. I have owned many of their guns and they are always reliable. The FNX-40 is no exception. It's a great gun, but it's not the best gun in the world.

I have only put 50 rounds thru it not one problem y. I am a huge fan of FN Herstal and this is my first purchase from them. I was a little skeptical at first because I had never heard of the FNX-40 before, but after shooting it for the first time, I knew that this was the gun for me.

I was looking for a new gun and I found this one. It's a FN Herstal FN FNX-40, which is the same as the FNP-9. The price was great and it came with all the accessories I needed. I'm really happy with my purchase!

I just received my new FNS 40cal yesterday after ord and I am so impressed with it. I have never owned a handgun before, but this one is perfect for me. The grip is comfortable and the trigger pull is smooth. It's also very accurate and easy to use. I would highly recommend it to anyone looking for a reliable handgun that's easy to use!

I am a gun enthusiast and I have to say that Sportsman Guide has the best selection of guns. I was looking for a FN Herstal FN FNX-40 and found it on their website. It was easy to find and purchase, and they had the best price out there. I will be buying more from them in the future!

I have had my FNS40 for about a year now and I have put about 500 rounds through it. I love the gun. It's not too heavy and has a good weight to it. The recoil is manageable, even with the 40 caliber round.

I'm not a gun expert, but I know what I like. The FNS 40 is the best gun I've ever owned. It's lightweight and easy to handle, but it packs a punch. The night sights are perfect for low-light shooting and the magazine capacity is great for those long days at the range.

I was a little skeptical at first when I saw the price of the FN Herstal FN FNX-40. But after reading reviews and doing some research, I decided to give it a shot. The gun is absolutely amazing! It's lightweight, easy to use, and has a great design. The only downside is that it doesn't come with a case or holster.

I have been a Sig fan for years and this pistol is just like the Sig Sawyer. It's accurate, reliable, and has a great grip. I love how it feels in my hand and it's not too heavy to carry around all day. I would recommend this pistol to anyone looking for a new gun!
