Great .45 ACP option!!!Review by Kenneth
Ok, this week I picked up the FNX-45 Tactical. Sam, I thank you. When I got home I cleaned it out of habit, but it was perfect before I started. I loaded up the magazines, 2 with range ammo, and one with 3 rounds each of 5 different hollow points of various flavors, 3 being +P. I put on a Vortex Venom Red dot, laser sighted it at 20 feet and waited for Saturday morning. I went up to McMiller, with my new toy and rifle that needed more sighting in. I sighted in the rifle, and then went to the 25 yd. range. I love this gun!!! It shot 2" inch groups first time out at 25 yds. It was a pleasure to shoot. Even the +P rounds were not notable mixed in. I had no issues, save on the Second magazine I hit the magazine eject button, and the magazine fell out. Doh. I was worried that the ejected shells might hit the Red Dot, but that was unfounded. It was easy to stay on target. This might be the best .45 ACP pistol I own (XDm 5.25" barrel, Remington 1911 R1 Enchanced, Glock 21 being the competition). This gun is big, Even with a outside the belt holster, I am not sure it can be used for concealed carry unless I lose some weight or buy a full size jacket. So after about 120 rounds, the FNX-45 tactical is really growing on me. I might like this better than the 10mm options! (Posted on 8/26/17)

Firearms Policy

How to Buy a Firearm or Ammunition

Federal firearms laws prevent the sale of a weapon from Red Dot Arms, LLC. directly to an individual in another state (we are located in Illinois). We must ship your firearm directly to an FFL Dealer near you. The steps to follow are:

  1. Order your firearm online using our secure shopping cart. If you know the FFL dealer you are going to use at time of order placement (not a requirement) enter his name and address into the 'Ship To' field.
  2. Find an FFL dealer near you that will accept the transfer of the firearm for you. Most sporting goods stores and pawn shops will provide this service for a small fee. Also, gun clubs, shooting ranges, etc. may provide this service to you. If you don't know which FFL dealer to use in your area, put a comment in your order and we will help you locate one near you. We have access to a large list of dealers in the USA that will gladly handle a transfer for you. Most dealers charge around $25 for a transfer. You must confirm the transfer with your local FFL dealer in advance.
  3. Next, have the dealer send us a copy of his signed license if we don't already have it on file. To check whether a license is on file, contact us. Please Note: It is now legal for us to accept a faxed or e-mailed copy of your dealers license! 
  4. Make sure the dealer knows the firearm is coming from Red Dot Arms. If you used a dealer that we already have on file, call him to let him know that a gun for you is on the way.
  5. We will send you an email when the firearm ships, which will include a tracking number.
