That is quite typical from insecure losers who spout sexist bull**** and need a "big caliber" to make them feel special. Children can shoot a 1911.

Women tend to prefer 1911 over the M9 because the single stack magazine means the grip is easier to hold with smaller hands. The real reason for the switch was likely caliber standardization with NATO, everyone else used 9mm.
Unless your a grumpy old man today who was around during the late 70's and 80's and was paying attention to what was being said off the record when REMF's wanted to dump the M-1911 A-1, lets put it this way, the U.S. Air Force was saying that to many of the females weren't able to master the M-1911 A-1.
The .45 ACP M-1911 A-1 is a very hard pistol to master. But once mastered it's probably the best combat pistol ever produced. Even males have a problem mastering the M-1911 A-1 chambered for the .45 ACP cartridge.
The reason the 9MM Parabellum was adopted was uniformity and logistics, because that's what all of the other NATO countries have adopted.
Why did Barreta win the contract ? Because Colt and Smith and Wesson dropped out of the competition because they developed a better combat service pistol but with quality comes the cost of manufacture. Barreta was the lowest bidder.
As we have seen, American SOP forces dumped the 9 mm pea shooter soon after and either went back to the M-1911 A-1 or another pistol chambered for the .45 ACP.
The Marine Corps has already announced that it's going back to the .45 ACP M-1911 A-1.
Re: "big caliber":
It's part of the American culture and tradition. Unlike the Europeans, America was always a big bore rifle and pistol nation. The 45/70, .30 cal Krage, 30-06, .308 Winchester (7.62), the .45 Long Colt and .45 ACP.
Why did the U.S. military adopt a varmint cartage (Remington .223/5.56 mm) for the AR-15 and M-16's ? It was the U.S. Air Force who pushed for the U.S. Army to adopt the AR-15 which would evolve into the M-16 A-1. The 30-06 M-1 Garands were to much of a rifle for airmen to handle so they adopted the M-1 Carbine. But the M-1 Carbine was really just a replacement for the .45 pistol during WW ll and didn't get the job done when trying to protect air base perimeters.
Yes, there are some women who prefer the .45 M-1911 A-1 over the pea shooter, it feels like to them they have a penis between their legs.
