Solitar,I'm 6'2", 250 lbs,take a size 52 coat, rarely wear a wrist watch because I can't find a band that will fit, and leave the area fragrant with newly made testosterone when I walk through. I've survived one war, three prison riots and a couple of Cub Scout camping trips. And no shotgun of mine has ever had only a PG nor will they.
PG only shotguns are vicious kickers. I've more experience with them than most, for years it was my job to shoot them and teach others to also. A 5 round demo stings,10 rounds or more can hurt.
The kick can be dealt with to an extent by training and practice. What cannot be improved is the plain fact that it's harder to hit with the $%^&* things than with a shoulder operated weapon.In crises, one heckuvalot harder. And those are the last places one needs extra limitations.
If one is committed to the idea that short range scenarios are best dealt with by hip shooting and PG shotguns, fine. Just do not expect either reality nor myself to agree.
