I think it bears noting that many people look at the 1911 and the BHP and see the common lineage and assume John Moses Browning built a refined version of the 1911, and that the BHP is something he sorted out rather quickly by just fixing issues with the 1911.
This is not actually what happened, though I think the use by FN of Browning's name in marketing the pistol helps foster the belief. If you look at the pistol that would, eventually, evolve into the BHP as it existed at the time of Browning's death, it's hard to see any hint of a 1911 lineage externally. It was striker fired, the controls did not in any way mimic the ergonomics of the 1911, and it really did not look much like an HP-35 even, except for the curving backstrap. It did feature an evolution of the 1911 barrel and breech to the linkless format -- but that was about it.
The design at the time of his death does not appear to have been something destined for immortality -- no fault of Browning's of course, since he was dead and could not complete the refinement of his basic patent. It probably did not help that he and the FN design folks were working towards French military requirements that were probably overly optimistic for the state of the art at the time.
The "1911's little brother" lines of the HP-35 were all done by D. J. Saive after Browning's death and, more importantly, after the protections on Colt's 1911 patent lapsed in 1928. Without any patent issues to contend with, it was easy for Saive to solve problems by cherry picking the 1911 (plus making his own significant contributions to the design).
So . . . the Browning High Power ultimately did not reflect JMB's vision of how things could be fixed on the 1911 to improve on it, but rather reflected Saive's vision of how Browning's 1911 could be used to put an unfinished Browning pistol into working order.
The end result was a brilliant piece of pistol design, but should really be regarded, in final form, as Saive's work with a big dose of copying from Browning, rather than something Browning designed himself.
On the issue of whether a .45 ACP BHP would have proved more popular in the US than the 1911 . . . I don't know.
Between the fact that the 1911 predates the BHP and the fact that Colt and FN's marketing agreement concerning Browning's work meant that no BHP's were available for sale in the US until after WW2 really gives the 1911 a big head start on the High Power. Shooters are a conservative lot for the most part, and something that worked for almost 40 years before the BHP entered the market would tend to have an edge. Add to that the familiarity of two generations of mass-draft soldiers from WW1 and WW2 with the 1911 and I think the 1911's status was set before the Browning could be purchased in the US.
Also, I don't think a double-stack BHP in 45 ACP would, necessarily, have been a winner. The HP-35 feels great in the hand, but widebody it with 45 ACP and I don't think it would feel as well (but willing to give it a try if someone were to start making them today
).
Just seems that if the design was improved and better that you go withthe better one. Or maybe it's becasue it was on the losing side of WW2.
The Canadians lost World War 2???
The BHP was the preferred pistol of our Canadian and British allies, and not something I'd really associate with the Nazis (they kept the factory running, but it's not like it was a P-38 or a Luger in the popular imagination and such). So I don't think that is really it.
ALL that said, I'm pretty much with TNT -- I'd love if folks like Kimber, Springfield, etc. started cranking out a product line of High Powers are elaborate and varied as the 1911 choices we have in the market today.
In the absence of such, I'm just going to have to "settle" for getting a Yost-Bonitz SRT package on my HP Standard, I think, to show the die hard 1911 guys I know that a Browning can be absolutely drool worthy as well.
