One of the handguns that resulted from the post-WW2 interest in standardizing arms among the future members of NATO was a lightweight version of the Canadian produced Browning High Power. Experiments began in 1947 to create first a lightened slide by milling out unnecessary material, and then additionally with the use of machined and cast aluminum alloy frames. The first major batch of guns consisted of six with milled alloy frames, with two each going to the Canadian, American, and British militaries for testing.

This would reveal that the guns were in general quite serviceable, except that the locking blocks tended to distort their mounting holes in the alloy frames under extended firing. The cast frames were generally unsuccessful, suffering from substantial durability problems. The program was cancelled in 1951 by the Canadian military, and the last United States interest was in 1952. The example in today’s video is one of the two milled frame guns sent to the US for testing.
