A shoulder holster is a convenient way to carry a pistol, especially if you spend most of your time sitting. The holster cliff there gives you the ability to fasten the belts so they fit different body sizes.
The best shoulder holster performs two functions: for holstering your gun and for one or two magazines. Isn’t that amazing?
Two holsters on both arms give you a sense of balancing on the strap and distribute the weights across your shoulders.
