EVERY gun is a compromise of sorts. Shotguns usually run with greatest power and speed, whilst giving up range, accuracy, ammo capacity, etc.
This gun adds concealibility (for a longarm) and ammo capacity at the cost of SPEED, and perhaps (shotgun) accuracy.
I’ll stick with my r/s Remington 870 for a while.
Wouldn’t a home defense weapon need as wide a pattern as possible? Why not a sort of blunderbus barrel end? Worked well for our forefathers at the cabin door.
