Sorry my bad.No generally you want higher capacity for the competition, you don't want to have to waste time reloading trying to clear a course. Some of the open class guys have some ridiculous looking setups like mag tube extensions that stick out 12" past the end of the barrel. I've done a few events have shot in open class and tactical optics.
There is two shotgun company in Turkey , they are really produce competitive class shotgun for Pro Shooting.
Main problem i didint find it in USA pages maybe they are marketin under diffrent brand name.
First one is Ata arms
8+1 Dual Valve system
Second Huglu Veyron Sport
11+1 Capacity , this is sporting Monster coming with Ceracote coating, light trigger
