MIM Parts Breakage in New S&W Revolvers

[Mark IV Series 80]

A poster on Pistolsmith.com has advised us of failures of two MIM triggers on recently-manufactured S&W revolvers:

Have you had any MIM parts fail?

 

[C.R.Sam]

No.
Interesting tho.

With MIM, the process is good. Sometimes the execution is iffy.
Just like any other metal forming.

High stress concentration in the area depicted. Improper radiusing at that point could easily lead to fracture.

Anything I said would only be construed as bias, instead of a comment on S&W's continuing poor quality control processes...

Mike,

Not by all of us... please share.

I hope I don't?

Haven't had a problem yet, with either my Smith & Wesson
629-5, 5" Classic .44 magnum; or 686-5, 6" .357 magnum.

Best Wishes,

By all means, share. We need our Savior's wisdom.
