I have never used a shoulder holster, but from that pic it sure looks like a jolt would knock the gun straight out, which would be ... embarrassing. Therefore, I must be wrong.
How is it secured, exactly? Is it just the grip of the leather? If it's not glued in place, then I guess it works, though
Paddle holsters aren't really designed for concealment. They're designed for LEOs whose duties require them to frequently take off and put their guns back on -- when entering and leaving a jail, for example.I have a Fobus paddle that I love but does not conceal well enough for my needs.
I don't want to carry something that bothers me all day
