Ive had an 11-87 sp 12 ga for many years, and it has been a dependable accurate firearm. I shoot open sights, and have the rifled choke tube on it. Out to 75 yards it is quite effective for deer, as it will shoot 3 inch groups with foster style slugs.
If I needed to, I would buy it again. I have the walnut, straight stock on it, I dont know much about thumbholes, but they sure look and feel nice.
Good Luck,
