Disagree. Shotgun it's extremely hard to master. I can sit a full weekend with a new shooter and them very proficient with an ar. It takes years for a casual shooter to be competitive with a shotgun. Keeping a shotgun fed is extremely hard, then trying to get 2 rounds on moving target with a pump is even harder. Add low light, maneuvering indoors with an 18"bbl, keeping multiple targets tracked while pumping...
Shotguns are easy is a myth.
I had some pumps but they are not for me as you say. I found the 930 Mossburg and never looked back. Owned a few and had pretty solid performance on all but 1 that I bought from and Ingo member that lied about the gun. Go figure. But I repaired it and it was flawless with just a bit of effort on my part.
Pump guns rock. I like them well enough but with age comes choices.
