Pocket holsters here will be generally separated into front pocket and back pocket holsters. Convertible holsters incorporate both – basically a complete front pocket holster with a removable back panel so it can be used either way. They could just as well be a jacket pocket, glove compartment or purse holster.
Pocket holsters are molded to be slightly less snug than belt holsters. Draw is accomplished by a thumb push-off reinforcement, or a pocket hook, or both.
