You might want to know what’s a good trap gun for the money. I like over and unders but some people do quite well with semi autos.
If you want an auto, the Remington 1100 trap guns and the Beretta 391 are great guns. Just get an adjustable comb.
As for double guns, the poor mans trap guns are the Browning Citori and the Beretta 682 and 687. The Browning XT trap is seen often. They will both stand up to competition for years.
As for pumps, the Remington 870 trap guns have won lots of shoots. But in the beginning, don’t be afraid to shoot what you have. Especially just playing around at your club. The main thing is get out and shoot. And try as many guns as you can before buying. Most trap shooters are generous about letting new people try their guns.
