The 4-Five .45 handgun.

The 4-five is a .45 handgun used in limited numbers by both NATO forces and the Livonian Defense Force 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 being fitted with the MRD red dot sight. Along with muzzle attachments, the 4-five also has an underbarrel rail that supports being fitted with a flashlight.

Suppressed 4-five. Although not currently fitted, the MRD sight would be mounted onto the hub just above the hammer.

The 4-five is classed as a heavy pistol and is often favoured for use by NATO/LDF officers and recon operatives.

Thanks to the greater stopping power of its .45 ACP round, the 4-five makes for a powerful pistol at close ranges. Compared to NATO's standard-issue sidearm which fires less hard-hitting 9 mm ammunition, the 4-five can put down most targets that aren't wearing heavy plate carriers in two or three hits.

At the same time, the primary downside to the 4-five stems from its low muzzle velocity versus the P07's 9 mm round. Consequently, this also means that the 4-five is heavier to carry while also possessing a much smaller magazine capacity (11 rounds versus the P07's 16- or 30-round magazines).


  • Green: Olive green slide with a black-coloured frame. Used on LDF 4-fives.
  • Sand: Flat dark earth/sand paint finish. Used by Mediterranean NATO 4-fives.

The 4-five only accepts a single magazine type. It has a "mass" value of 7 units:

.45 ACP 11Rnd Mag

Contains 11 rounds worth of .45 ACP ammunition. Does not contain any visible tracers.


  • 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.
    • Its name may also be inspired by the "Five-seveN" of the same company, both of which have names referencing the ammunition they fire (the 4-five using .45 ACP, the Five-seveN 5.7×28 mm).
  • The model itself appears to 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.
