Nice shot and nice hog. I didn't know Kimber made a 10mm 1911. Pretty cool.
Domestic hogs are euro-boars. Where do you think hogs were domesticated from?
Except for genetics and some extensive craniometric analysis, there aren't any reliable phenotypic traits that will indicate a connection to recently (last 100 years or so and like everywhere else, Texas had importers) imported truly wild Eurasion hogs (aka Russian boars). Many of the phenotypic traits people point to are traits common to the species in general or common to hogs reverted to feral (leg length, hair qualities, tail curl, musculature, snout shape, size, aggression, etc.). Note that domestic hogs, feral, and Eurasian all the same species.
