The 4-five is a .45 handgun used in limited numbers by NATO forces in ArmA 3.


The 4-five is a polymer framed, semi-automatic handgun chambered to fire the .45 ACP round.

It loads from 11 round magazines and can attain a fire rate of up to 600 rounds per minute, with a muzzle velocity of 380 m/s. The 4-five supports having the MRD red dot sight mounted onto the nub just above the hammer (designed exclusively for use on it). Along with muzzle attachments, the 4-five also has an underbarrel rail that supports being fitted with a flashlight.

The 4-five is classed as a heavy pistol, and is often favoured for use by NATO officers and special forces due to the greater stopping power of its .45 ACP cartridge compared to NATO's standard-issue sidearm, which fires less hard-hitting 9 mm ammunition.

At the same time, the primary downside to the 4-five stems from its usage of the same .45 ACP round. It has a lower velocity compared to the 9 mm cartridge used by the P07, and also means that the 4-five is heavier to carry while also having a much smaller magazine capacity (11 rounds versus the P07's 16- or 30-round magazines).


  • The 4-five is based on the real-world "FNX-45" handgun designed by FNH USA, an American division of the Belgium-based arms company FN Herstal.
    • Oddly enough, the in-game counterpart can only load 11-round magazines despite its real-world version being capable of using either 15- or 10-round magazines.
    • The model itself appears to also have been ported for use in "DayZ", another title designed by Bohemia Interactive where it is called by its real-life manufacturer name as the "FNX45".
  • The 4-five was not initially included on ArmA 3's release. It would only be added with the release of the campaign's first episode as part of Game Update 1.04.
  • Initially, the 4-five could only accept a muzzle suppressor and the MRD optic. The ability to attach a pistol flashlight on its underbarrel rail was eventually added with the release of Game Update 1.70.
