I have a Model 66 3" Carry Comp, and use to own DB's Model 67 3" Carry Comp. I agree with his assessments. I've shot a Model 19 3" Carry Comp, and helped a friend acquire one. I'll mention this thread to him.
Be prepared to spend about a grand. But they are definitely worth acquiring. They are a gateway drug, however. I have a 66, 640 and 642 Carry Comp - all are very useful tools. Put a pair of VZ grips, or a pair of cocobolo Spegel's on them, and you are living in the lap of luxury.
All three pistols are listed in my will, and that's got a waiting list, too.
