Can anyone tell me how the "Sporting" model of the Urika 2 is physically marked as-such on the gun itself? Also: what exactly are the differences in a "Sporting" from a "standard?" How about the "Trap" (saw a nice-fittiing "Trap" at the gun shop, but no help there for these questions.) I've seen bits and pieces of these questions here on SGW, but no definitive answers. Thanks in-advance wonderful and patient Forum-folk!
