The "fits you properly" is more important than the "built for the sport" part, IMO.
It's a shotgun. if it throws a decent pattern at 35-40 yards, you'll do fine (Yes, Skeet and SC generally has closer targets, but if you have choke tubes, you can easily adjust), IF THE GUN FITS YOU.
When you shoot a rifle, you line up the sights with the target, and apply slow, steady pressure to the trigger until the shot is fired. If you do that with a shottie, it's called a miss.
Don't over-think it. SCs are the closest to "real" hunting - different presentations, yardages, and stances - find a field gun (double, auto, pump) that fits you, and you'll do fine.
I tell new Trap shooters: Shoot what you have. When one bird out of 100 really makes a difference - then get a specialized gun.
And, when one bird of 100 makes a difference....you'll be confident enough in your own abilities and capabilities to make your own choice.
