SXS guns, straight stock, splinter, barrels at least 28”, no ejectors, unless they are Darne ejectors, double triggers, checkered ebony, horn or checkered butt, truly prefer no recoil pad. No ventilated ribs, thank you very much. I hunt grouse, woodcock and pheasants. IC and IMod get it done, usually.
O/U guns, I really only use them when it is too cold for double triggers and need gloves, single trigger, somewhat tighter chokes, Mod and Full, usually pistol grip, since that is typically how they come. I’ll switch the O/U off with an A5 16 gauge Standard, with either a full choke Sweet 16 27” barrel, or, the barrel it came with, a 26” IC, depending on what I expect.

I have other guns, but, those questions weren’t asked.

Best,
Ted
