All depends on YOUR situation. Particularly what's behind your target and potentially in your house (family member) or close neighbor. If in protecting my family with SKS at hand, I would certainly not feel under-gunned. Earlier I saw posted about birdshot not being effective...not sure I would like to be hit in the face or chest with 12 gauge birdshot at 5 to 10 feet and would possibly feel better about drywall pass through into my kids wall.
