Deadeye/Virtuoso weapon speculation

After looking at the teaser a few times I think part of his kit might be centred around the gun in one of three ways:

1. While it might just be cus of the flashiness of the teaser, there is a possibility that the gun may have magical properties, similar to Lucian's guns, but using actual bullets.
2. The gun is a revolver, signified by the very intricate and outward cocking hammer. While most pistols have a cocking hammer, revolvers, especially old-west style ones, tended to have longer, easier to access cocking hammers since they were not semi-automatic (they wouldn't fire until they were cocked back). This also means that he may have an ammo system similar to graves
3. The gun could possibly be a repeater, or use some other kind of cocking mechanism, since you can see and hear him reload at the gun at the 45 second mark.

Again, these may all be for the flashiness of the trailer, but it could give us an idea of what the new champion could do
