H&R Pardner questions

[Guest ChattownKA]

So i picked up a pardner pump the other day at the gun show for less than $200. I know it was modeled after the 870. Are after market accessories for the 870 interchangeable with the pardner? 
example: Will a Blackhawk stock with a pistol grip designed for the 870, fit on a pardner?

or if y'all know of a site that sells pardner accessories, please send me the link i haven't had any luck so far.

 

thanks in advance

Physically they will fit but the butt stock screw is metric so you have to find a metric screw or tap it for a SAE screw.
