Entirely different beast. I have no problems shooting 12ga high brass - I catch the recoil with my body, rinse, repeat.
Bout three years ago I had my first and last go with a Kel Tec KSG. It belongs to one of my brothers. He was loaded with powder puff in one tube and high brass in the other. He had not told me about the high brass tube, but he swapped to it when he handed me the KSG. It was a major dick move that spoiled me on the KSG period. Catching high brass on a solid shoulder hurt like stank. He laughed. I handed him his KSG and told him that was a dick move.
Point of sharing that story is this: The S2k would not be near as fun with recoil management slowing things down. The MFT Minimalist made thee recoil a non issue. My shoulder simply does not like the size/shape of the Gen 2 factory buttstock. It’s like a 7 year old poking me in the same spot on my ribs … repeatedly. The 7 year old ain’t powerful, but getting poked in the same spot repeatedly just hurts.
