Looking for a pump shotgun. Went to a local gunshop and the fellow showed me a HK Nova. I was impressed with the features. The saleman said he been selling more HK Nova than any other pump and has had good feedback from owners. My question is if this gun this good or is it to early to really know? I know it cost about 70 to 80 dollars more than the 870. Also my not sure if I like the one piece stock and receiver. Thanks for your time!!!
