I read you about the custom gun business--tough row to hoe, for sure. But (the big BUTT), you might take on a few jobs now and then just to test the waters, and then make it your retirement hobby/business when you get there. Some of us NEED to work, and I'm guessin' you are one.
Especially like the snubbed extractor rod housing on that last GP. Many people who do that job leave too much non-functional metal there. Don't approve of trying to make a GP into a J-frame Smith, but I think it could lose a little weight up front if it's gonna be an everyday carry gun (Wish Ruger would offer the half-lug versions again, but as well as the "fatties" sell, that's not gonna happen! Glad there are guys like you who can MAKE it happen.).
