Mike---I'm assuming its 12ga? Is this a Model of the 1100/11-87 series or just a totally different gun? What is different on it compared to the 1100/11-87? Just curious as i am not familar with this Model.
return mechanism is in forend, rather than buttstock like an 1100. 870 stocks interchange, and 870 bbls can be drilled for gas ports and will fit 58s. Extremely fast cycle time, and that was their main problem, they could break action bars as a result. Once very popular with skeet shooters as they were somewhat weight-forward. Basically, the 1100 was the same gun with the return mech. moved to the butt.
