One of the most commonplace real-life variations of the UMP makes use of 9×19mm Parabellum cartridges, and that spherical is already general in Tarkov’s ammunition financial system, together with the .45 ACP. Another variation, the UMP40, fires .Forty SW rimless pistol rounds – which are not found in Tarkov at the moment.
That’s now not to say Battlestate doesn’t plan on including them, however. .45 ACP, in spite of everything, turned into introduced alongside the M1911 pistol returned in May. So it’s absolutely everyone’s bet as to which ammunition the UMP accepts – it may be any or all of them, on account that there’s room in Tarkov to switch top receivers round as you want.
That stated, 9×19mm Parabellum is already used in as a minimum 12 guns in Tarkov, whereas the .Forty five-caliber round is only currently usable with the M1911 and its M45A1 variant. Adding an SMG that fires that cartridge may want to Escape from tarkov roubles make it a greater in-call for (i.E., useful) spherical in Tarkov. The immediately magazine in the photos above in addition suggests this is the .45-quality variant.
