UMP45

The UMP45 is a NX variant of the UMP Submachine Gun. It is found to have more stopping power (damage) and a pre-attached iTech Red Dot Sight for reduced Bullet Spread when zoomed in. Nothing else seems to be noticeably different between this and its original GP model. The inability to add Telescopic Scopes onto the weapon seems to restrict it to medium to close ranges only, but players could still be lucky enough to take enemies down in further ranges.

Trivia

 * Due to its name, the UMP45 uses the .45 cartridges, the strongest variant of the UMP series. That makes the original UMP in Combat Arms most likely be a UMP40, which uses the weaker .40 cartridges, with specialized 35-50 round magazines.
