I have a Kimber 1911 in 10mm which is a higher pressure round than the 45ACP and 40S7W. Matter of fact I just fitted a Barstoe 40S&W barrel to it and have shot a couple of dozen each of jacketed and lead bullets. It's comfortable and accurate. Went to 40 to shoot lead loads, hard to download 10mm below 1000 fps, and brass is cheaper.
Got the Kimber over a Dan Wesson because the barrel is fully supported in their high pressure calibers.
I also have a Para Ordnace in 45ACP and like it also.
My son has a Kimber in 38 super and it's very accurate and comfortable to shoot also.
That's what's so good about the 1911, it's versatile and comfortable to shoot and easy to point.
