I think there is some truth in what he says on "production firearms".
But in the last 5 years - I've bought guns from mfg's like Sig ( an X-Five that came with a test target ) - a few 1911's from Wilson Combat that all came with their own test targets as well - and a 1911 Monolith Les Baer that came with its own test target.
When I put down $ 2,500 plus on a new gun - I still expect it to come with its own test target / and I think at that price point, they need to be spending more time on the gun to make sure it is what its supposed to be. If I send a gun to Wilson Combat for re-work, major refinishing, etc I will request, and pay for, the gun to be test fired.
Do I think Kimber test fires their guns ( no, not even out of their "sort of Custom Shop" with the Raptor, etc ), do I think Sig testfires their Revolution series 1911's ( no ) let alone their standard model 226's, etc ( no ) - but they should consider it and charge us a little more. I understand Glock has driven the expectation of price down / and some guys think they should be able to get any gun at a Glock price. Some people drive low end cars and trucks and some people choose to drive a Lexus .....and I would expect more from a Lexus dealer - just like I do from Wilson Combat - and I expect to pay more for the priveledge. Its a free country / and I'll pay for the kind of mfg'ing and service I want - and its just fine that way - and I don't really care if Glock or Kimber test fire their guns or not. If I choose to buy one / I should understand that.
