About the UMP-45 | Grand Prix
UMP-45 | Grand Prix is a Restricted skin that drops from one of the 42 CS2 weapon cases, the Chroma 2 Case.
Valve released the Chroma 2 Case on 15 April 2015.
Each open has a 3.9950% chance (about 1 in 25) of pulling it, as one of 4 Restricted finishes. One in ten of those drops is StatTrak.
It sits in tier 2 of 5 (Mil-Spec to Rare Special) and ranks #41 of 45 finishes in the Chroma 2 Case by top-wear Steam price.
It sells for about $1.72, against $7.77 to open the Chroma 2 Case (case plus $2.50 key), so even its best wear is worth less than one open.
