While my main HD/Tactical shotgun is a pump (FN Tactical Police Shotgun) I am liking autoloaders more and more.
I understand the argument and logic of the "rack-rack" to scare the bad guys...but I think that Hollywood is partly to blame for this.
If I am defending my life, property, or loved ones, I would prefer to reduce the threat via (if needed) lethal force, rather than let the bad guys know where I am at with the racking of the slide.
(I suggest keeping your shotgun locked and loaded in the same manner/condition that you keep your primary HD handgun)
I have a Franchi Law12, and im getting ready to pick up a M1 Super90 when the right deal comes along.
Once the M1S90 comes in (in SBS configuration) it will become my primary HD shotty.
