Released in November 2018 via the Danger Zone Case, the UMP-45 | Momentum sits at the Classified tier within The Danger Zone Collection.

The float range for this finish is restricted to 0.00–0.50, so Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred are the only obtainable conditions on the open market. The restricted range is set by Valve at the time of release.

A StatTrak™ version is available, which tracks confirmed kills made while the skin is equipped and typically commands a premium over the standard finish. Active listings for UMP-45 | Momentum are tracked across 17 marketplaces, with prices spanning $4.03 to $143.82 depending on wear, variant, and seller.
