Oddly, it just seems to be the ‘pedigreed’ guns, regardless of breed, that drown.
The gun show mongrels without papers, vaccinations, or neutering seem to be able to swim just fine from day 1.
I have to say that one of the best mixed breeds have to be the Stripped lower receiver/lower parts kit and upper receiver AR-15’s
A nice sport utility rifle with a good mix of genes and a fair avoidance of the 4473 inbreeding that is more common with the pedigreed varieties.
