The 4-five is a .45 handgun used in limited numbers by both NATO forces and the Livonian Defense Force in ArmA 3.
Overview[]
The 4-five is a polymer framed, semi-automatic handgun chambered to fire the .45 ACP round.
It can only load 11-round magazines, and can attain a fire rate of up to 600 rounds per minute[CfgWp 6][Formula 1] with a muzzle velocity of 380 m/s.[CfgWp 7] 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.[CfgWp 8][CfgWp 9][CfgWp 10]
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 stopping power of its .45 ACP cartridge[CfgAm 1] and the 4-five's 11-round magazine[CfgMa 1], the 4-five makes for a decent pistol at close range. Compared to NATO's standard-issue sidearm, the 4-five can put down most targets that aren't wearing heavy plate carriers in ~ 2-3 hits.
However, the primary downside to the 4-five stems from its low muzzle velocity and poorer accuracy compared to the P07.[CfgWp 1] Consequently, this also means that the 4-five is heavier to carry while also possessing a much smaller magazine capacity (eleven rounds versus the P07's 16- or 30-round magazines).
Ironsights[]

The 4-five's ironsights uses a fixed zeroing setting of 50 metres.[CfgWp 11] It is not possible to manually adjust this to a different setting.
Its ironsights feature three illuminated dots for use in low-light conditions (two on the rear notches and one for the front sight post). In daylight, the sights will be coloured in white with a green dot in the centre. In darkness, the white dots will no longer be visible and will be covered by the (glowing) green dots instead.
Camouflage[]

Trivia[]
- 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.[2]
- Its in-game name is possibly inspired by FN's "Five-seveN" pistol, both of which have names referencing the ammunition they fire (the 4-five using .45 ACP and 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 referred 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.[3]
- 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.[4]
- The 4-five's model was also changed by the patch so that it now has functional night sights (the front and rear sights originally did not glow under low-light conditions).[4]
- The Green variant was not originally available upon release and was only added with the Contact expansion pack (as part of Game Update 1.94).[5]
