I shoot a revolver using the duty holster I carried in LE, (Hoyt Brake Front) and speed loaders, Six loaders work find for my M-64.
Other then that, Lots of ammo, I aways take a lot more then I need. It don't spoil and if I don't shoot it this time, I'll shoot it next time.
I'd recommend not buying anything (but ammo) and using what you have until you find out which way you want to go.
