bartholomew's analysis may not hold water.
colt m1911 a1
overall length 8 1/2 inches
weight 38 ounces (2.375 lbs)
cz97b
overall length 8.35 inches
weight 2.5 lbs
The 97 is slightly shorter and only weighs about four ounces more. It also has a ten round capacity. I'm not sure what 3 rounds of .45 averages but if weight was THE issue, don't put em in.
As far as carry goes I would consider them both "BIG" carry guns. If you can carry/conceal a steel framed 1911 I think you could manage the 97b as well. I think the cz reliability might well offset the slight size and weight disadvantage. I never really thought it was that much more or less concealable than a 75b or a 1911.
1911's
I have yet to see a 1911 for less than I thousand bucks that could even approach the reliablity of the 97. Now as I prepare to get flamed, I know they are out there, it's just that I've never seen one. At the range the other day A guy was shooting a Kimber with a $200 after factory bbl and while it grouped very well at 50 feet from the bench, it usually had some sort of malfunction or two for virtually every mag(new barrel was not broken in though, but still!).
97's
To be fair, a shooting buddy had a 97 that would shoot everything but winchester silvertips. I was damn near called a liar on this forum for saying that, believe it or not. Yeah, that's what I do, I have nothing better to do than sit around and make up stuff about guns. The accuracy is superb but not quite on par with the 75b(opinion, not tested).
