BHP is a fine gun. Great design, and the manufacturing execution in Belgium, Canada, and later Portugal was excellent.
Having a trigger that could be tuned to target grade was not a requirement of the design, so it is not logical to criticize the design on that basis. Yes, the 1911 has a tunable trigger, but that was not a requirement of the US Army spec, it is merely happy accident. It would be like criticizing the design of the 1903 Springfield rifle because it does not have a 30 round magazine.
John Browning might be the greatest firearms designer in history. If not the greatest, than he is in the top three. I think the Gaston comment was meant as a joke... had to be..?
