hiya gt. planning on buying a 12ga shotgun this weekend. have it narrowed down to the rem 870 express or a benelli nova. any advice? looked at them both today, kinda leaning towards the nova, weighs nothing and takes all sizes of shells. had a mossberg 500 years ago but sold that. looking to spend under $400. can i still upgrade the sights and all that jazz on both? thanks.
