It would be nice, but how does shipping in and out of the states work?
Easy; just don't 'ship' across the border. Instead, take a three week vacation in the US and bring your revolver. Mike's turaround time is two to three weeks including shipping time. And all 'perfectly legal'.
As for name dropping a custom gun smith his name is Ian Jones (myself). I make no statement about better than any one else but I am good with an India stone, and the locking mechanism is easily removed if your really that concerned about it. Either way I'm happy with it, and that's really all that maters to me.
Bully for you! I guess high standards are not for everyone.
If you read the description of Mike Carmoney's action work, the internal lock can simply be removed if lightening the hammer is required. At the worst, this means that the trigger pull must be a couple ounces heavier if you need the gun to be IDPA compliant by retaining the lock. I seriously doubt that there are many shooters good enough to tell the difference.
To date I've had four of my revolvers 'Carmonized' (S&W Models 19, 66, 610 & 625). I've had 'trigger jobs' done by some Canadian smiths (admittedly, I've never used Charlton) and Mike's work is by far head & shoulders above any of them. He is also a multi-discipline revolver Master class shooter so he knows what's needed in order to be really competitive.
Not all action jobs entail lightening the hammer. Many users prefer to retain single action capability and/or do not wish to limit themselves to using Federal primers. There is more than one way to skin a cat. M.D. Charlton did an action job on my K-38 and they did not lighten the hammer; I'm sure that one of the foremost S&W tuning shops in Canada knows what they're doing.
Although I've only 'dabbled' in PPC (more than 10 years ago), all the serious competitors that I remember had 'bobbed' hammers on their revolvers. And IIRC, they also used Federal primers exclusively. I guess it all depends on how competitive an individual wants to be.
All my 'Carmonized' revolvers retain single action capability although I don't see a situation where I might need it in a competition like IPSC/USPSA, IDPA or ICORE. That being said, I do practice engaging the single action notch on my 'Carmonized' revolvers 'at speed' and it's not that difficult to do.
I spend quite a bit of my disposable income travelling to matches. I go to those competitions in order to 'place' the best I possibly can. I'm going to ensure my equipment is the best that I can afford (including state-of-the art modifications and tuning) in order to meet that goal. YMMV.
