1oz, we're on the same page. IMO, Pumps are great for GP use, field guns and so on.
A skeet, trap or SC gun is as specialized as an Indy car.
An aside, I recall reading the match results of a SC tournament.The scores between HOA and 20th place were,IIRC, 10 birds apart out of 200. Each and every bird counts heavily, so top competitors are using what gives them the best chance of hitting that each and every bird.
Let's fantasize a moment. Kim Rhode and I are shooting, she with her well worn Perazzi and I with an equally worn 870.
She kicks my butt.
Next, same game but we swap shotguns.
She kicks my butt again. Her scores may be slightly lower, but not enough to matter
in a head to head contest.
For someone seeking gold in the registered sports, a pump may not be the best choice, even if it fits and is well known to the user.
For Joe Shotgunner out to have fun and get better with his shotgun(s), OK.
And it's still the Injun, not the arrow....
