Released in February 2014 via the Operation Phoenix Weapon Case, the USP-S | Guardian sits at the Restricted tier within The Phoenix Collection.

The float range for this finish is restricted to 0.00–0.38, so Factory New, Minimal Wear, and Field-Tested are the only obtainable conditions on the open market. Battle-Scarred examples are not produced, so the most worn copies still retain a relatively clean appearance.

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 USP-S | Guardian are tracked across 18 marketplaces, with prices spanning $2.82 to $17.63 depending on wear, variant, and seller.
