Yes, there is an M37 trap gun. And chances are you will never see it or the BPS trap model in the winner's circle.
Can't argue with you there, obviously the OP cannot afford a Trap specific Perazzi ( nor can I ) but has not mentioned a desire to compete in Trap. He does state a desire to shoot more trap "for now" but looking for a gun to shoot 90+% Sporting ( Trap, Skeet, Sporting & 5-Stand ? ) 10% Field use.
I might reccommend perhaps a used or new Browning Maxus stalker as an all-around clays & game gun. They will cycle target or hunting rounds in lead or steel. One can get a few extended chokes for easy change on the Sporting clay course, shim adjustable stock for fitting and has the same lop, drop at heel and toe as the sporting version.
I think I am talking myself into getting this gun
