Looks a lot like the Remington Factory folding Police Stock I purchased 20+ years ago.
First 5 rounds were okay but after that standard 00 rounds were starting to "bite" the shoulder and cheek.
Bought it originally for bear protection up north.
Given the abundance of short barrel shotguns - I'd use a 12" barrel coupled with a short LOP Hogue and get a gun I could actually practice with in order to become proficient with it.
