Shooter
For me, the grab in an instant gun is a handgun. With shotgun I have a little more time to think when I grab it so I want the option of buck or slug and even choice of larger buck or #4 buck for my first shot.
Main reason is safety/legal purposes of going with smallest load possible to kill a coyote or dog whe I step outside, AKA #4 buck.
Gotcha, I keep all of my firearms except for the two I always keep nearby(my EDC Glock 17 & my Taurus M85ULSS backup/house/bathrobe gun) in my gunsafe, so basically my plan of action is to fight my way to my gunsafe, immediately upon opening the gunsafe I can retrieve a fully loaded & ready to rock 590.
