First shotgun

Hey guys so my buddy shoots trap/skeet and im very excited to be going with him to shoot but i want to buy a shotgun, now i want it to perform for those activities but also want it to sit under the bed so preferably a semi auto. My price range is around a thousand bucks so please let me know what you guys would recommend. As far as barrel lengths also im wondering if i can make it with a 26” or should i go 28-30. Recommendations!
