I would bet it was not the holsters fault!
I would agree.... Operator Error. :yes4:
Although....the Flash Bang is a great idea. I just don't see it as the best option. And I say that because..... IWB and OWB require a nice sturdy belt to hold up the extra weight.
With the Flash Bang - you should be required to buy a special bra to help support it. Bras come in various sizes, shapes, styles, etc..... and they're not designed to hold something at the center point. Depending on fitment, bra size, bra integrity....I can picture the holster flopping around and not staying in the upright position (as it should).
Granted, I haven't tried it..... or maybe I'm just over thinking it..... More often than not - between an oversized or undersized bra fitment, the girls flop around on their own and you don't need an extra 2lbs (example) in there. But that's just me.....
