For home defense?.....I imagine my 21" barreled 870 SP Turkey gun will do just nicely......I'm sure just about any larger diameter bird shot will do just fine for close up work. Just need to remember to slip in the modified choke...... In the unlikely event I ever need it, that Super Full choke might require a few gallons of paint to correct.[]
Retrofit a tac light and sleep in peace.

Could there possibly be a more intimidating noise than a 12ga. pump racking a shell in the darkness?
