No, it doesn't. But it certainly won't hurt it to have been there.
I don't think anyone on this board ever said you "needed" this equipment. I think the discussions get out of hand because some people think anyone with modern gear must be a Ninja. I don't belittle anyone who wants to use their single shot shotgun as a HD weapon, good luck to them. Everyone can have an opinion, but just because you might prefer older and simpler equipment does not mean you know anything more than me.
Here's a pic of Browningguy the Ninja:
Good gracious, he's wearing camo, must be a ninja. Well, I was stalking on a friends ranch, he also wears camo when hunting so it seemed ok at the time. And you'll note the entrance wound from leaning against a tree at about 140 yards.
Here's one of Browningguys Ninja guns, look out, it has a 6 position stock and a scope, Browningguy must be a Ninja.
I'm sure there is no obvious reason, like Mrs. Browningguy also shoots this rifle and likes a 1.5" shorter LOP. Nah, couldn't be anything like making sure the gun fits multiple users, must be a Ninja.
So you carry your model 10 and H&R single shot shotgun, I'll carry my Mossy 500 with extended mag tube and light, or an AR with optics/free float tube/tuned trigger, and one or two of my BHP's and we'll both be happy.
I almost forgot, here's one of my Ninja BHP's with a fiber optic front sight (and a tuned trigger). I know, it's very Ninja, but my splits went down by a tenth so it's staying.
