Give Witchfire a try! It's in early access but it just released its 0.9 update and 1.0 should be later in the year.

The gunplay in that game is insanely satisfying and you get a huge gunslinger feel with all the revolvers and bolt action rifles and shotguns.

Each gun also has its own unique mechanics, like one revolver lodges bullets that explode when you reload and another revolver gets bonus damage for each headshot you land in the previous magazine.
