I have a whole selection of 13.5" to 16" shotguns in various gauges... .410, 20gauge, 12gauge. Pump, single shot, over/under, lever, mag fed pump... I really need to take a group shot, if for no other reason than to try and remember what I already have so I don't accidentally buy (another) duplicate.
Other than the mag fed, which is mostly just a range toy, the rest of them get used practically. Once you get used to the shorter barrel guns, it becomes hard to convince yourself to grab a long barreled shotgun from the cabinet. I'll hunt grouse, harry maggies and crows at the farm, pick off rabbits, use them in the spring gopher shoots (when you can get up close and wipe out 3-6 in one shot while they're poking their heads out of the hole). Good bush/pack guns.
They're just so much easier to handle, in almost all conditions, than something with a longer barrel.
I don't hunt migratory, where a longer barrel for a bit of extra velocity and the "swing" balance comes into play. If I'm shooting clays, I will grab one of my full length guns, though.
The biggest thing I've found, is that with the short barrel guns, chokes matter a LOT more. You get some crazy wide patterns with cylinder bore, but can really tighten things up with a full choke. This is especially true of lighter shot in the #6 to #8 range. Heavier shot seems to hold together better (cylinder bore works fine for 00 buck).
In short (ha!)...
Buy it. Shoot it. Come Luke, join us on the dark side.
