Can't say that I have found Colts that delicate or troublesome. Some parts require fitting, some drop in. I changed out a hammer in a Detective Special this past spring and it was a drop-in perfect fit.
I been carrying and shooting them for over 30 years now. In fact when I became an LEO in the late 70s, we furnished our own weapons. The guidelines we had were a 4 inch, .38 or .357, Colt or S&W ~ period.
Lack of gunsmiths? I have always sent mine back to Colt when I needed a gunsmith. Not only will they fix and repair them, but are great as far a having a vintage gun refinished. The Colt Custom Shop is also fast on turn around and very reasonable in price.
