I pretty much shoot sxs shotguns, primarily hammer guns, almost all the time, including casual skeet and sporting clays, except on the trap field (most of my sxs are choked C or I/C and Mod). It's cause for comment at my club when I show up with something other than a sxs. I do have a handful of O/U guns and one lonely pump (a much worn Winchester Model 12 16 gauge with a Weaver choke system), but could happily live without any of them as long as I have the sxs.

As an aside, the Weaver choke system is so ugly it makes a Cutts look attractive.
