Appearances[]
Shadow of Chernobyl[]
A reliable weapon. As a quality compact close-range weapon, it is very popular among the Zone veterans.
― Shadow of Chernobyl in-game description
The UDP Compact has significantly better firing rate compared to other .45 caliber pistols and very light, weighing less than 1.00kg.
However the UDP seems to be susceptible to jamming, which makes it slightly unreliable in extended firefights.
Acquisition[]
In Shadow of Chernobyl, the UDP is heavily employed by veteran and Expert Freedom members as their sidearm and sold exclusively by Skinflint.
It can also be obtained from the stash Goodies in the safe in the Red Forest.
It is used as a sidearm by the following characters: Barin from Duty, Charon from the Monolith, Father Diodor of the Loners, Leshiy, Lukash and Murk from Freedom.
Clear Sky[]
This trustworthy weapon boasts German quality and reliability. The compact short-range weapon is especially popular with the Zone's veterans. Uses .45 ammo.
― In-game description
In Clear Sky, the UDP Compact is used by expert members of Freedom and some experienced members of the Mercenaries and veteran Loners . It is still very light, weighing at less than 1.0kg and its magazine can be expanded by 4 bullets to have a total of 12 bullets per magazine. It has a better firing rate than other .45 caliber pistols and retains a degree of accuracy and power, though not as powerful nor as accurate as a Kora-919. Most technicians can upgrade the weapon.
Acquisition[]
It is sold only by Ashot, though one can salvage one early in the game while fighting the mercenaries in the Dark Valley. The player can only buy this pistol from Ashot after attaining a friendly reputation with Freedom. It can be retrieved from the Dangerous stash in the Red Forest.

- .223 pistol - an unused variant of the UDP Compact chambered in .223 FMJ that is found in the game files. It is a reference to the namesake weapon from Fallout 2.
Call of Pripyat[]
Impeccable reliability and durability combined with excellent accuracy are the main noteworthy features of this weapon. Its minor drawbacks include its considerable size, relatively high center of gravity and massive bolt, which make it difficult to conceal but do not outweigh the weapon's positive features. The weapon is especially popular with the Zone's veterans.
― Call of Pripyat in-game description
In Call of Pripyat, the UDP Compact is one of the pistols that can be modified to have a new firing mode – in this case, fully automatic. It is the only .45 caliber pistol with this upgrade. It can also mount a silencer.
Compared to its previous iterations, the pistol now has a 12-round capacity by default, which can be upgraded to 16, making it the best non-unique pistol of the game capacity-wise behind the HPSS-1m.
Acquisition[]
The UDP Compact is used by Mercenaries, Loners, Freedom and sometimes even Zombified Stalkers. All of the mercenaries encountered during the side mission Kopachy carry it as their sidearm.
The UDP Compact is sold by Hawaiian after obtaining the achievement A Friend of Duty, and by Owl after obtaining the achievement One of Ours.
