Looking to get some feedback from firsthand users on the 500 Turkey/Deer combo. I have never owned a 500, but I have a lot of time behind the M590 while in the Marine Corps. I love the 590 platform but the only Mossberg shotgun that I have personally owned is the 930 JM Pro which was great. But how are the new production 500 & specifically the Turkey Deer gun? Is the slug barrel accurate? How do they wear, are there any issues to know of? My other option is an 870. I prefer the old Express from when Remington was on top (90’s and older), but I am considering a new 870. I know the old 870s very well, but I have only handled the new versions and they seem decent. Thoughts on either?
