Dear Reb- Our Browning High-power, the service issue pistol for most of the British Armed Forces, were proofed to 13.5 TPI, as a matter of interest. Built by Inglis of Canada for the Army, or FN for the RAF, they had to share the rather hot Mk 2Z ammunition used in our Sterling SMG. This weapon fired using the so-called advanced firing pin system, where the firing pin was actually machined into the face of the breech block, and fired the round as it came to an abrupt halt in the breech, stopped by the case neck stopping against the inverted neck shape of the chamber.
