[IM_Lugger]

If wanted to convert .40 barrel to 10mm and have the caliber designation changed as well, who would be the most qualifiled smith to do the job?

anyone used Armco for this? Is anyone better?

You might contact Casey (ARWENACE). He is in the GTA and does good work. A lot of guys on here have used him.

It's a pretty simple job. Gunnar could definitely do it. In your neighborhood, there's Double Tap Sports, Omega custom and Rodger Kotanko who would all be capable.
