The main plus of the 1100 Competition is the factory overbored barrel. But the buttstock is NOT a trap stock. If you want to use it for trap you may wind up having to buy a trap stock. The 1100 Competition is more along the lines of a Sporting Clays gun.
I would suggest aused Remington 11 11-87 trap gun that comes standard with a 30 inch trap barrel that is backbored and a trap stock. You can pick up one in great shape for around $600.00. I have two of these and love them. Feel free to PM me if you have any questions. JM
