I'm a Mossberg guy, but if the Rem 870 "Fits" you better, that is the way to go. Got a distant relative that like the Win 1300 best....go with what fits.
I'm suspecting that maybe your 3rd or 4th generation of grandkids MIGHT be able to wear out that shotgun, but you probably can't.
Now, buy ammo by the trailer-truck-load, and see if you can disprove the theory of low long a modern pumpgun lasts......
