Guns are the Sheriff's thing. Unlike knives, which the Murderer gets, the Sheriff's gun fires one shot that either wins the round or loses it — no pressure. Every gun plays the same (one bullet, one kill). The difference is all in rarity and look, which is what drives trade value.
None of them do different damage — it's one shot either way. So "best" is cosmetic. Some players swear by godly guns with particle effects, but those effects can actually block your aim. If you're playing to win, a cleaner model with a clear sightline might serve you better. Pick what feels right in your hand, not what's worth the most.
Guns trade the same way knives do, with godlies at the top. But matching sets — a knife and gun from the same series — are worth way more than individual pieces. Collectors pay a premium for the full pair. If you've got one half of a matching set, hunt for the other half before selling. The combo price beats selling them separately every time.
