Anyone have a TK 9mm conversion done lately?

I see on their website that TK Customs is offering a machining package on the customers cylinder that will allow it to shoot 9mm as well as 38/357. Sounds to good to be true and I'm wondering about accuracy and reliability.
However the price and simplicity is attractive.
I was thiking about a conversion for my 627PC .

I just converted a 686-3 from 6 shot 357 to 7 shot 9mm. In the next week or 2 I will try it out with 9mm and 38 Super target loads and 38 Spec. and 357 Mag. and report back in this thread. I only work on my own guns for various reasons. I don't know if my conversion is any different from TK Custom or not. I do know that they do high quality work and have a good reputation. I like their moon clips the best.

The 9mm case is a good bit larger at the base than the Special or Magnum, and slightly larger than the Super. I'm thinking the rimmed cases might have a shorter than normal life if shot and reloaded a few times.

I shot the (revised) 7 shot 9mm with different loads today. Everything loaded, shot, and extracted fine. I fired 9mm, 38 Super, and 38 Special, all light target loads, and 357 Mag. The 357 mag cases bulged out some at the bottom, as expected, from the higher pressures. Not too badly, they could be reloaded. I would advise against it because of the possibility of case head separation. The light target loaded ammo did fine. The 9mm and 38 Super were on moon clips and the 38 Specials were just loose rounds. I will only be shooting 9mm in that one, but it was an interesting experiment.

TK Did My Model 66-2

I found a second Model 66 non recessed cylinder for my Model 66-2 on an internet firearm site and had it fitted/converted to 9 MM by TK's (they do excellent work) to my existing Model 66-2 revolver, and it works/functions just fine. The 9 MM round is slightly larger than the 38/357 round so some shells may expand and tend to sometime stick in the expanded 9 MM cylinder, so I would recommend finding an extra cylinder, and this way you have a convertible revolver, and keep the original host revolver stock so as not to alter the value of it plus adding value to it with the 9 MM cylinder.

Thanks Gents. I was hoping to avoid sending in my frame for a new cyl to be fit but it sounds like the way to go. I think I'll hunt up a spare 38/357 cylinder and have TK (or other) do the conversion.
