If gunslinger only gets one new weapon, it should definitely be a revolver, chambered to something "more powerful" than .50 AE, to fill the tier 3 role. I think the OP's got it right going with the typical option, a monstrous, shiny S&W 500, fitting the role perfectly. Maybe with a scope or reflex sights, but that might delve too far back into Sharp Shooter territory, and/or look ugly. My main point though, is that making the revolver weaker than .50 AE doesn't fit the needed role.
Also, if I remember correctly, the HC-specific ammo pick-up wasn't made by TW themselves, it was part of a third party mod/map, so that wouldn't be reliable, since the source isn't TW. I think it's safe to assume that the squad members know what their guns are chambered in, 50 caliber fun time, and that the mag capacity is unrealistic for gameplay purposes.
