.50gi pistols

[iron horse]

I am searching for a method of obtaining .50gi caliber semi auto, all metal, da/sa, exposed hammer pistols. The inventor of the .50gi, Guncrafters Industries, does not offer such pistols or conversion kits for this type of pistol.

Does anyone know of a gunsmith or shop that could convert an existing pistol to .50gi or create a .50gi pistol?
Thanks for any info.
