Question

I’m building my first Glock using Gene Shuey’s methods as found in the AGI Glocksmith course. I’m nearly ready to have the slide and extractor hard chromed. I’m wondering where Gene sends his, or at least if anyone knows a place that will do the job so that the mirror finish and the matte finish will still be visible after the hard chrome process is done. Everyone I’ve called says that it either will be all shiny or all matte. I need to know someone who can do what Gene has done. Thanks for the help. Ryan
