I do have advice, I hope you read this pgrundle. First I'll let you know I "have" tried shooting trap with a tactical barrel shotgun ( Mossberg 590A1 SPX 20" barrel?) and let me tell you something, it was terrible. You want to shoot trap, you gotta have a long barreled shotgun. I tried a Beretta (I have no idea what model but it was semi and had a really long barrel the kind you hunt with) and that hit 20/25 clay targets that launched outwards from the bunker trap house.
So yes barrel length for me did make a massive difference. If you are just doing some random milk jugs/melon blasting, go tactical. If you want to make the shots count and shooting flying orange clays, go non-tactical long barrel classy 12 gauge that usually has wood stocks on them.
Oh and for the record, it's really expensive shooting trap. Had to pay for ammo and clays too so look out for that and consider your budget. Super lucky the shooting club president lend me a shotgun to try out for the first time. Shooting trap has 2 types, the kind where you throw your own clays manually or by some form of launching machine and you shoot whenever you are ready and the other kind is the one where you are with 4 other people and you need to pay attention to whos turn it is to shoot before you call "pull" into the mic. I found the later a bit more stressful as it forces you to always be aware while a rifle range is the most casual where you shoot whenever you feel comfortable with no time constraints.
