One thing I noticed, is when they deliver the gun to the owner to shoot. After
they fire it, the guy grabs the gun out of their hands. WTF is up with that?
I would probably butt stroke him for attempting that with me.

Those scenes take place away from the shop and at the customer test firing, they haven't completed the sale, including running the NICS check so he must retain posession of the firearm or he's transfered the firearm without a NICS check and could lose their FFL. If you "butt stroked" him for that, you'd find yourself in jail or shot in self-defense.
I try not to pay much attention to the prices in the show - they're doing a lot of custom work, including a lot that likely is never making the show. However, I was very surprised to hear the $800 price tag for the paint job on the zebra print M&P, however it was done by an outside shop that specialized in custom paint jobs and appears to have been a custom designed hand air-brushed finish on the slide, frame and back-strap. The paint lines also flow between pieces despite them being painted seperately, so there's some skilled labor involved in that piece.
As for the kid's engraving ability - can't really judge it until I see it in person, the detail work that they've shown on the show looks pretty good, but even in HD on a large flat screen, the true detail of good engraving is impossible to see.
I like American Guns much better than Sons of Guns. More real gun smithing and less "game changa" hype.
