I haven't acquired one yet. Though it's definitely something I'd like to obtain. I use a lot of handcannons (namely Devil You Know and Red Hand IX) and that thing looks like pure sex in revolver form. If you find one or buy it from Xur (he's sold it twice, now), snatch up the Red Death. Performance and stat-wise it's comparable to Super Pox VLO or Fair & Square. A nice high-impact, extremely accurate pulse rifle with a decent magazine size. Damage-wise in Crucible, it takes two bursts to the head to kill an opponent, or three bursts to the body (which usually ends up including a headshot as the recoil rides the bullet path up to the face and neck when aiming at center-mass)... at longer distances it'll take more, but the thing is a surgeon's tool even from across the map. People end up sitting on this weapon for PvE because each kill kickstarts the health/shield regeneration (making it god-tier for Strikes) but the description of "This weapon is a Guardian killer." holds very, very true if you've got a steady aim and are willing to break away from spamming Auto Rifle bodyshots like the rest of the Crucible.
