personally, the most reliable firearm i have experience with. i've never seen an issue with one that couldn't easily be fixed with cheap replacement parts and a little know how, if it even needed that. dead on reliable. no staked in parts. never seen an extraction issue. never had a jam. nothing. minor feed issues i have seen, due to bad mag springs or a bent cart. stop, and i promptly corrected these issues easily and quickly.
my favorite firearm. purists can cry about "forearm rattle", or "aluminum receivers" and "cheap feel", while conveniently neglecting the fact that they by and large go bang each and every time you pull the trigger. so yeah..
it's a keeper. as much as i love the win1300 and while there are things i really like about the 870, there isn't a thing i'd change about the 500.
