I bought four new S&W's in the last year - two 2 5/8" PC627 UDR's, a 3" 63, and a 3" 60 Pro. All were perfect, mechanically, and even had good B/C gaps - .005-.006" - measured post breakin (Actually, measured this AM!). The Eagle-made boot grips on the UDR's went back for exchange - via their FEDEX Ground pre-paid label - for just the grip! I finally got a gap-free fitting set - and decided they were too small for my use, enjoying both revolvers with other grips - a common result here.
When they state a price for an 'action job', it includes FEDEX overnite both ways from and back to your street address. If you don't like the finsh on your 442 after carrying it in your sweatty pocket for years, they have been known to pick it up, refinish it, and return it - gratis. They won me over nearly five years ago when I stupidly destroyed my 629MG. They paid the s/h to 'look it over' - sent an overnite FEDEX label for the body bag - then quized me re it's ammo - was it homebrew, etc. I was honest - it had only launched my reloads. They called back and said it was a stuck bullet in the chamber causing the chamber to overpressure and burst - not their metallurgy. They couldn't replace it - but they would sell me a new 4" 629 off the assembly line for ~$270, inc s/h. it had to xfr thru an ffl - the dealer didn't even charge me - that was nearly five years ago. S&W is top drawer in my estimation.

PS If you elect to have your dealer ship your new S&W back for you, you normally pay the shipping - and it will be a lot more than the $14 it costs S&W en masse for FEDEX Overnite.
