Ok, you got me!
This is the first year I've bought a new gun in 13 years -- back then it was a flawless PC 500, which even after all the rounds through it, still looks like it did back then. This year I've picked up a 360PD, 60LS, M&P340, and finally the 640 Pro I mentioned earlier.
Of all the NIB Smiths I've bought (going back 40 years), not one had cosmetic, mechanical, or any other issues... until the 640 Pro. I was lulled into believing every NIB Smith was flawless and didn't really need to be viewed through a magnifying glass before being carried out the shop's door.
It was daylight in the shop when I picked up the 640 Pro so I didn't notice the dead Tritium front sight (till that night at home). And I would NEVER dry fire a gun in the shop so, again, the lousy, gravelly trigger didn't show itself till I got home and tried it with snap caps. The factory solved those two faults but refused to address the cosmetic issues.
Inasmuch as I've come to accept the ugly milling on my 640 Pro, I sincerely appreciate -db-'s take, and as I promised the factory CS guy, I've bought my last new Smith. It wasn't an idle threat, but he didn't really care. I should not have to "inspect" a new gun the same way I do an old one. I've bought six used guns this year, and none have had the issues I encountered with my NIB 640 Pro. I'll continue to buy used Smiths, after a thorough inspection, or course.
Cheers,
Bob
