I have an 1100 slug gun and the auto helps a little with the recoil. But the auto is quite a bit more expensive than the 870 slug gun. both will be very acurate once you find a slug it likes... all guns having a mind of their own. Mine will cut holes at 50yrds and hold 3" or less at 150yrds. Mine is factory bought. Couple buddies went to pawn shop and bought the cheapest 870 they could find then one put rem barrel on his and other used a hastings. Both shoot really well... They came out a little cheaper but they took the time to hunt down a deal on the gun...
