|«|| The 4-five is a polymer-based semi-automatic pistol named for using .45 ammunition. The reliability and accuracy are the most appraised features of this weapon. This weapon is favored by firing drill competitors because of an eleven round magazine and the available collimator sight.|
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 the MRD red dot sight designed exclusively for it, and can be mounted onto the nub just above the hammer. 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 higher stopping power of its .45 ACP cartridge compared to NATO's standard-issue sidearm, which fires less hard-hitting 9 mm ammunition.
The primary downsides to the 4-five stem from its usage of the .45 ACP round, which has a lower velocity compared to the 9 mm cartridge used by the P07. This 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 is only capable of using 11 round magazines despite its real-world version being capable of loading from 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.
