As a first gun,do not get a revolver you will have a bad time. Fumbling with shells under fire never ends well. later on down the road when you have more experience or board and want a challenge then go for it.
I use my revolve in CQB(FPS mod) when I feel like a challenging game. Really makes you focus and think about everything around you when you have to reload under stress.
And make every shot count,you only got six.
