Mil-Dot,
I respectfully disagree with your statement that pistol grip/shoulder stocks are superior.
The stock/pistol grip combo unit allows the most versatility,the shooter can shoot from the shoulder, but also can hold the gun closer in
Do you mean that more AR style stocks are collapsible "__ Position" and that is why they are easier to hold close, because you can change the length of pull and overall length? or are you talking about tucking the stock under your armpit?
I see no reason why you could not hold the shotgun in such a matter with a conventional stock.
The PG also affords a firmer,more stable platform when shooting from the hip than a traditional stock does.
When shooting form the hip, I find that any type of AR style stock gets in the way more than a conventional rifle/shotgun stock. Personally, I think its also a little slower to bring the gun to bear with an AR style stock, not much slower, but a little.
I think there are some areas where a conventional stock actually performs better than an AR style stock. The two that come to mind are shooting supine, and reloading.
I haven't had a chance to play around with shooting a pistol gripped shotgun from the supine position, but a with the conventional stock, it was pretty ergonomic. It looks like the grip angle of a pistol grip shotgun would bend the wrist at an uncomfortable angle.
As far as reloading, if you bring the muzzle up and rotate the gun like you would a pistol or AR, the conventional stock keeps everything in line with the forearm. Now, your just holding the weight of the gun, and allowing the stock to provide a little bit of leverage against the fore arm. If you have a pistol grip, its still doable, but I IMHO it puts more torque on the wrist, and its harder to get the stock to comfortable line up with the wrist.
That said, if you have a way to run the gun that works well for you, that's really all that matters.
YMMV
