Weapon | Sediment sits in the Hot Radiation collection at uncommon rarity—the tier where you are usually filling a themed loadout, not chasing flex drops. The read from afar is unmistakable: gold topographic contour lines wrapped around the slide, like someone pasted a survey map onto a sidearm. Hydrographic finish on a metal base; the flavor line “I saw it too…” is short enough that it mostly shows up when you are swapping guns mid-round, not in your face on the menu.

Release & where it drops

March 31, 2025 — shipped with the Spring Forward update and entered circulation through Hot Radiation. Same playbook as sibling collection skins: unbox, Steam trades, or listings on C5GAME and Steam Community Market. If you are building Hot Radiation piece by piece, Sediment is often the low-stress slot before you spend on rarer names in the set.

What actually matters when you buy

Wear runs 0.00–0.68, so you are not locked into factory-new only. Lower float keeps the gold lines sharp and the metal plate clean; mid and upper wear thins and breaks the contours—more “weathered map,” less crisp survey. Because the pattern is line-driven, the float number is only half the story. Spin 360° inspect and zoom:

• Slide top — do the rings stay continuous or “snap” into gaps?
• Grip & mag well — common friction zones; broken lines here ruin the whole look in first-person.
• Listing photos vs in-game — thumbnail screenshots lie; match density and line direction in inspect before you pay.

Theme still reads on a small pistol canvas—good if you want quiet metallics with detail, not neon shout.

Loadout pairing

Gold contours play nice with sand, olive, deep green, and brown tactical bases. In a Hot Radiation goal kit, Sediment often acts as the cheap glue between louder pieces.

Shop verdict

Worth picking up if you want Hot Radiation flavor without uncommon-plus pricing drama. Skip or hunt harder if you need pristine, unbroken contours everywhere—then budget time for inspect shopping, not just the lowest float. Steam Market and C5GAME are both fine starting points; always confirm in-game before checkout.

Editor’s aside

Uncommon line skins are a trap for lazy buyers: two identical floats can look nothing alike once the slide is scuffed. I treat Sediment like a map print—I am buying continuity of the rings, not a badge. At 0.68 cap, a “surveyed but worn” float can still be fun if the breaks land where your HUD hides them. And that one-line flavor? Perfect for the moment you pull the pistol and immediately wish you had stayed on rifle—no essay required.
