Here's my saga...which worked out well in the end...but made me wonder about S&W's quality assurance program...or the lack thereof...the gun really should never have left the factory.
I bought my M63 in Dec of '20 planning on using it as a fishing companion in my fly vest. On my first range trip, however, it locked up after the firing the first several cylinders. In addition it was spitting lead on half of the chambers, peppering my face and firing hand.
A call to S&W, (then doing service in the old Springfield MA factory), got me an understanding technician & a FEDEX shipping label and I had the gun back, fixed, in less than 3 weeks, IIRC.
The service guys had replaced the cylinder, hand and yoke...and done a rudimentary action job while they had it. Their fine work resulted in a first rate, walk the dog, light plinking and fishing gun that I now really enjoy.
Accuracy runs to ~ 1" at 10 yds from an unsupported "Weaver" stance with CCI Mini-Mags and Federal Auto-Match ammunition, which I can barely beat shooting off sand bags.
Here it is below, in its alternate role as an understudy for my usual CC piece, the M60 with Hogue "Monogrips". The grips on the M63, BTW, are an early set of Smith Combats that really fit my hands. The only thing lacking to make it perfect would have been a Baughman Ramped front sight, like the M60, to replace that abomination fiber optic.
Best regards, Rod
