I may have missed it in your earlier post but what is the reason for buying a gun? Is it for self defense like CCW, competition, general target shooting, duty carry?
When I gun shop, I look for the "perfect" gun that will fit my needs. Smaller is not always better when it comes to guns. For example a mini 9mm gun will have more "felt" recoil than a full sized .40 or .45 sometimes. Lighter weight guns generally seem to kick harder also.
The 1911 design is timeless. It has withstood the test of time and remains to be possibly the most popular handgun ever made. It, however, can be finicky and is undoubtedly more difficult for assembly/disassembly then most modern handguns.
Although, I have never fired a 9mm 1911 or BHP, you may be able to find a gun shop or friends that will let you shoot theirs and you can make a better decision based upon how they feel to you.
Good luck in your hunt
