100% Manufactured in America, Veteran Marine Owned and Operated, all done right here in Arizona. Started out when I pulled the lock out of my 329PD and went lookin for a Titanuim part set to fill teh hole. No Titanium parts set existed so I'm a machinist as just made my own then figured I'd offer em to the rest of the world in Titanium, Ordnance Steel, and Stainless Steel. Winds up being 12 models you can pick from. I do all the metal finishing myself by hand all parts are checked for quality and consistency, if I wont put it in my gun it's not going in yours. You have a Smith with a lock in it, I make the parts to fill the hole when you pull the lock out. I do all frames, J K L N X, if folks start asking for Z frames I'll do them to. Part sets are always on hand, ship same day or next work day.
