Picked up a police 870 wingmaster about 30 years ago. Not sure if it has a 18 or 20" barrel. It came with a cylinder bore and I had it tapped for choke tubes. Adding a mag extension gives an 8 shot capacity - which helps it swing better - (have to plug it for dove & ducks). I enjoy carrying an O/U. But after hunting pheasants, quail, dove, ducks, turkeys, and coyotes for many years, if I really want to be proficient at taking game...the 870 "Rooster Booster" is what I use. It is incredibly quick to get on target. It started out with a nice shiny finish. After the finish wore off and got a lot of "field character" I gave it a rattle can paint job.
A short gun is also a lot more effective than you think at a distance with the right choke tubes.
very nice gun, I like the rattle can camo job
I have the OEM Rem mag tube extension to take it to 8 rounds , I find it more weight than I like to lug around most of the time int he field walking, I will be putting it on for 3 gun this summer it may stay on if I get used to it.
the 20" barrel has room for the +3 mag tube to take it to 7+1 the 18" only has room for the +2 mage tube 6+1
want to talk about crazy we have a +8 Nordic tube for an 870 my son runs in 3 gun makes it a 12+1 shotgun it sticks out past the 28 inch barrel a few inches. try finding a case to fit that.
I know pump guns are not the norm in 3-gun or rather USPSA multi-gun similar to 3-gun but USPSA. we are probably the most budget multi gun shooters I have seen , it is great practice but my truck costs less than some guys shotguns.
in our class you can only pre-load 10 but I found a deal on the +8 round so I went with it
We had trap tonight , I don't get to shoot often at trap it is for the kids , but we were early and got setup with time to spare so I got a quick round in . shot a 23 missed the first bird and one in the middle that went left I was a touch ahead of it and backed off on the lead and broke the rest.
