Randomly following links, I encounter this phrase:
the full-size and compact models feature a new proprietary rotating barrel breech to provide lockup
Hmmm. Rotating barrel lockup. Colt, 2000? Steyr, 1912? Savage, 1907?
And I assume the name of the product, Px4, is pronounced "Pee-by-four." Right? Or did no one in Marketing run it by any 'Murricans?
