Some of you guys are clueless. If you truly think a Browning Hi Power will out shoot and/or be more durable than a good 9mm 1911, then you seriously need an education or wake up call.
The two platforms aren’t even in the same stratosphere. Regardless of how they were intended a century ago. The 1911 was designed around the 45 because that was the stipulation of the trial, not because it couldn’t work with other cartridges.

It wouldn't have been the same gun, if designed around the 9mm cartridge.
Colt made some prototypes in an oddball 9.8mm cartridge, the whole gun scaled down for the smaller cartridge, and shopped it around in Europe, with no takers.
The Spanish Star pistols, a long line of sort-of 1911s, were scaled to their chambering, not being .45-sized guns with shorter barrels and butts, but slimmer slides with shorter strokes.
In my experience, the 1911 is much more reliable when chambered in .38 Super and 10mm, than 9mm and .40, as the two former cartridges are the same length as .45.
.40 is/was a very popular chambering in USPSA competition, and literally everyone loaded it a tenth of an inch longer than SAAMI specs to improve feeding in 1911-based pistols; loaded long, it wouldn't fit in anything else.
9mm has benefitted from decades of magazine development, each new design being plugged as the one that will work reliably; ours has a spacer at the back! But ours has a built-in feed ramp at the front!
Super and 10mm run perhaps more reliably than .45.
