One could say that 260s are "PvE-only" sidearms... And that person wouldn't be lying. They are so bad that they are only good in a hand full of PvP scenarios.
Please buff them Bungie. Give them 10 points more range by default or improve their range accuracy. Something that fits that "Precision Frame" role. But do something. Literally every other RPM type is a better pick than them in PvP. "Gunshot Straight" perk won't change anything about that.

Kryothesia is quite usable due to its range.
