I'm very pleased with my purchase, this gun is very accurate and very little recoil. Very smooth shooting with the FNX .40 caliber and will be purchasing another firearm from Bud's in the very near future.

October 2, 2017Finally made it to the range with my newly acquired FNX-40. It was an absolute pleasure to shoot. The grip on the gun is awesome, just like the FNX-45, the recoil control was easy. Am truly considering the 40 for a new carry gun.

April 10, 2011Overall I like this FNX 40 very well. It is a solid value for the price and seems to be built quite well. The grip is a little wider than most other handguns so just bear that in mind if selecting this pistol. The magazine springs are very tight but hopef

June 15, 2010This gun seems to be a good value for the money. However, I don't think that there is much of a "fine quality" handgun here. I ordered this strictly for home defense and combat shooting so it will get many rounds fired through it along with some wear and
