I'm sure some guys do. The thing is any gun you have for carry is for personal defense and as such, you need to trust your life to it. ANY defensive handgun that goes boom every time that you can put on target is a viable option.
The vast majority carry modern handguns...in the long run cheaper imo. Holsters, night sights, trigger work , repairs , etc are easier to find and and over the long haul will make the investment in a modern gun a better investment and ultimately perhaps,, cheaper. And if you get a modern firearm from a quality company you get the assurance of a company that will stand behind the product.
Also, if you get the bug like I have it, you are going to want to '' trade up or sell up'' and C&R guns are less likely to be in demand so maybe harder to sell. I buy Rugers, Glocks, Smith's etc. If I decide I want to try something new I can sell any pretty quickly.
That is my 2 cents, but others here are more experienced and may advise otherwise.
