They are and always will be hybrid gimmicks that really aren't good for much at all.
Somebody didn't get the memo, because these guns have made .410 and .45 Colt ammo, brass, and bullets rather challenging to buy. I enjoy my 3" SS Judge and am keeping it, thank you.
I wonder if the dissing often comes from those who have never tried one of these guns.
Stories of shotshell pattern expansion and the hazards to bystanders are exaggerated. If a bystander is close enough for pie plate sized spread, one should not have taken the shot with any caliber.
