ADDED: I might end up keeping my stainless SS4, but if I manage to find a .38Spl Speed or Service-6 for the right price, I might go ahead and also pay the custon-$$$ to have it modded into my perfect "packer." But I have to still find that candidate piece to start with.

There have been a few posters at 24HrCF who had custom work done on their wheelguns - and of course that kind of 'smithing ain't cheap, it [usually] sounds quite satisfying!
