It would seem to me that you are a bit more fond of squirrel than I am!
Back when my knees didn't hurt so much, I used to use a single for snowshoe grouse hunting. The notion that you would actually be sucessful in this endeavor was silly enough that you could probably have carried any gun you liked, including a snub nose .38 revolver, but, my single was an Italian folding "Companion" 12 gauge, imported by Galeif, and with a 30" full choke barrel, it was useful as a balance pole while walking in snowshoes.
At least it was hammerless. Not that it would have mattered.
It was mostly an exercise in getting out of the house and getting some mid-winter exercise, but, I did have a grouse explode from a snowcave right between the tips of my snowshoes on several occasions.
I don't ever remember taking a shot.
Enjoy the new to you gun.
Best,
Ted
