Living where I live now, I really don't have much need nor desire for a house gun. But if I did it would likely be a KelTec KSG7 or very similar. I currently have an Ithaca 12ga 'Featherlight' for my occasional bird hunting, but some years ago ran across a real steal on an extra bbl for it and I bought it just for home defense where I lived at the time
It was a 28", IC choked, plain Jane bbl with no vent rib and a simple 'bead' front sight. Now it's an 18.5" bbl, IC choked, very plain Jane bbl with a very simple bead front sight. If I really needed a home defense gun, that would be it until I could find the KelTec and buy it.
Oh yeh, my CCW is still and will likely be for a long time ....... the Hellcat with the red dot sight. On rare occasions I'll still slip on the KelTec PF9 I've had for many years. I carried it so long before I got the Hellcat, it's almost like an 'old friend'!!! I feel bad for it when I see it there in the safe with "nowhere to go"!
