The SKS is good for longer shots,
but up close, a good carbine in the same caliber would be useful.
I’d suggest an 18 inch barrel for the Remington (870?),
and the acquisition of a 10/22 when they go on sale at Cabela’s next time.
Yes, it is an 870.
I’m not into modifying guns, so I’ll just leave it the way it is. For shorter shots, I need to get a pistol. I’m probably going to go 9mm due to the cost of bullets.
