Greetings, I've been thinking about getting into ppc with a revolver and am wondering if there's any benefit to buying a ppc revolver rather than building one up on my Model 19 (with an excellent trigger job). What should I expect to pay either way?

You could probably buy one off the auction sites cheaper than having one built. But.....it would be one that was built for someone else's preferences. If you want it done your way, have a good revolver guy build one to your specs.
