If your running revolvers use the Calvary division mostly for keeping your back protected but anyway. Equip the basic training shifty it has the advantage of giving you infinite ammo for your pistols plus 3 attachments plus the pistol will automatically fill your ammo clip when your weapon is switched to so I found out how cheap this combo was because all I have to do is switch to the shield and wait till I see the tip of the shield them switch back to have a full clip for my reichsrevolver so this also helps keep you in the fight because unlike you your enemy still has to reload at some point so this will definently catch them off guard this would also be pretty helpful with machine pistols.

I was just casually trying to get headshots with the revolver for my camo challenges and I completely forgot you can do that with shifty equipped so now I can play a little more aggressively with handguns.

Anyway hope this helps with anyone who wasn't aware of this feature or like me just ignored or forgot about it.
