I don’t like pistol grips myself, but the price seems good. I got a Mossberg 500 with the pistol grip only stock. It was used, in great condition for $125. I ditched the pistol grip and got a Hogue Youth Model synthetic stock for it and now it is a very short, handy 6-round HD 12GA that takes 2 3/4” and 3”.
I tried one of those shotguns with a pistol grip and no butt stock. The recoil was vicious.
Some people do like them but not me. I like the pistol grip but it also has to have a butt stock.
I have that Mossburg 500 as well...have an issue with my shoulder and figured a waist fired would be a nice choice.
