If memory serves, mossberg made a home defender 410 shotgun aimed at the female market. One of the things they were pushing is that a 410 slug had more muzzle energy then a 44 mag pistol.
Can you shoot a slug out of that pistol comforatably?
There is no way a 410 slug has the energy of a 44 magnum. It is probably close to a 357 magnum. I would rather just shoot a 45LC. Maybe not big in the energy department, but a proven man stopper.
