I lil advice here from someone who shot an 870 for turkeys since I have been hunting them. Take the time and visit the pawn shops and gun shops where the ya crept trade in guns. Find an older model 870 with the J Hook lockable safety in 26 in barrel. You can find them for 250-300 all day long. Maybe even cheaper. I'm sitting here looking at three different ones at a local pawn shop.
Anyway, get that gun and then order you a Remington Xtra Full Turkey Chile on eBay or Amazon. That choke with a #5 lead is an unreal pattern. I'm talking UNREAL. I have literally taken birds head off at 25 yrds.
The newer 870 are yugo. They aren't the same quality as the older guns. I retired mine this yr for a lighter 20g Franchi, but wouldn't be a thing for me to pull her back out. I had mine dipped in Bottomland and she is sharp looking!!
