One gun for everything? Now there’s a can of worms! In theory yes why not, but you won’t find many trap shooters using a sporter for trap or many skeet shooters using a trap gun.To be honest I have no idea yet. I'm going to try everything I can so I'm looking for a gun that is OK for all disciplines.
There have over the years been sporting shooters who used trap guns, sometimes modified sometimes not.
I think most people would go with the right gun for the discipline being shot.
