In January at my concealed carry class, the instuctor went over the various holster options. I’ve owned a shoulder holster like this officer has, for years. I was surprised when my instructor pointed out a few drawbacks of this type of holster. One was you are always pointing the end of the barrel somewhere that is not directly into the ground, it is pointed at a somewhat higher angle than that. As your body moves around, the pointing also moves in a sweeping manner behind you. He mentioned the remote possibility of an accidental discharge while holstered.
This poor woman must have been a lot shorter than the officer. Hard to say how the accidental discharge took place, but that’s why it’s called accidental.
I like my shoulder holster. The drawbacks of a purse-carry are too great, I’d never do that (yes I am a woman). I like how the shoulder holster keeps the weapon very close to the body.
I have several shoulder rigs...even some Jackass and Miami rigs. They are adjustable as to angle of the muzzle......it does take some time to get the right fit, however.
