This is why...
...I buy old S&Ws.
...I buy old S&Ws.

Last year I purchased online a new S&W 10-14. The double action was very rough, so I returned to S&W unfired. Two months later S&W replaced the entire revolver. The replacement was perfect in every way, in fact equal or superior to the many older Model 10 HB I have owned and shot in the past decades. Shoots to the sights out to 50 yards, quite accurate. After several hundred rounds it's proven to be excellent in every way.
So I figured it was time to try a new Model 36-10, despite having a peck of older I & J frames. These are rather difficult to find, with S&W selling mostly aluminium and scandium frame guns. Ordered one online from a well-known reputable wholesaler, and picked it up today. From all appearances, packaging, and lack of firing evidence, it appears NIB.
Well it looks like past is prologue. The barrel end at the forcing cone looks like it was cut with crooked hacksaw, which thereafter started chewing up on the cylinder face.
Yes, it's going back to the factory.
What was wrong with your 10–14 that caused a replacement of the entire revolver?...
No traditional American company I'm aware of builds 'em like they used to. Comes from having parts assemblers on the line vs craftsmen.
So now... over a month since my last post. Right after that I spoke to a supervisor at S&W who promised to "make things right" after the botched "repair". I returned the Model 36 Classic to S&W for a 2nd time.
Received a notice from FedEx that a package from SAW was on the way. It arrived today and I was hesitant to open it. The cylinder was replaced (again), and this time the barrel replaced instead of filed on with a chisel. Both the the inside and outside of the forcing cone were very sharp, but it was not making contact with the cylinder. Then I held it up to the light...
I'm beside myself at this point.
