The conventional wisdom seems to be that the buttstock on a defensive shotgun needs to be shorter than one on a sporting/hunting shotgun. I'm considering getting a Magpul stock set for my 590A1 to try this out.
The conventional wisdom also seems to be that an A2 buttstock on an AR must be replaced with a collapsible one because it's too long...but it's a perfect fit for me. I'm 6'1" and wear 34 sleeves.
I've got a few hundred rounds through the Mossberg and it seems fairly comfortable to shoot, but that's the extent of my shotgun experience, so I'm aware that there might well be something I'm missing.
I'm retired with a decent but not wonderful retirement income so I can afford to buy something that's worthwhile, but not just because the cool guys have it.
How do you figure this out?
