I've worn shoulder holsters of various designs for about forty years.
Make sure she tries it out. Reaching across the chest is an issue, and men who are barrel-chested and ladies who are, well, more "gifted" than others can have issues about getting a safe grip on the handgun.
perhaps this is a good excuse to do some hands on research.
Looking for a good shoulder holster for a small lady (about 5'3") to carry an SP101 3" revolver, and a speed strip or two on opposite side. She is right handed, medium build. Miami Classic from Galco usually gets recommended - any alternatives ?
thanks
A video reviewing the holster might be "helpful" for the rest of us
Flashbang is under consideration, but the consequences of an AD worry me.
