Maybe it was in one of those “Miami Vice” shoulder holsters, where the muzzle is pointed to the rear of the wearer.
My thoughts exactly. I carry a S&W 4506 in a Galco “Miami Classic.” However, I still don’t see how she managed to hit the trigger. I can’t begin to imagine how that happened. Furthermore, there is, of course, a strap that slides between the hammer and the firing pin, exactly like what you have on a hip, duty holster. Whole thing seems strange to me.
