Something I neglected to mention - the first time I shot a pistol grip shotgun, I started out with a full tube of Sellier and Bellot 2 3/4" 00 buck, LOOKING DOWN THE SIGHTS, RAPID FIRE. I handled it fine.
I thought I had the "feel" down, so I went to a full tube of low base 7.5. Handled it.
Got complacent, loaded up a full tube of 7.5, only there was an EXTREMELY hot 2 3/4" reloaded duck round (dunno exactly what it was but kicked harder than any 3" I've shot, honestly). So I'm going through the tube lax, right? I get to the duck load and the gun comes back and hits me right in the mouth. knocks out my right middle tooth and part of the one next to it. I kept shooting that day looking like a hockey player.
Since then I've gotten back on the horse and fired tons of rounds through them and kind of learned what works and what doesn't. It's an OK choice as long as you use suitable ammo (reduced recoil buck and slugs) and know how to aim it. It's a contact shooter at best but I would not feel outgunned with one at a close distance and some practice. Yes, I'd rather have the full stock.
