After a bit more than four years and 15½K rounds, last Saturday the MH Pin sheared in half on my Custom Classic. It was an original Kimber part.

Local smith who had a spare that afternoon siad he had never seen this happen before. Has anyone seen this before?

Could this have been a MIM part? Years ago just replacing the pin destroied the plunger tip on a Classic. I will never trust a MIM part again. Calthrop

Calthrop, I think it was because it looked liked "Pot Metal" inside.

I think I will replace a few more MIM parts.

Which parts are MIM? The best replacements are made by who? Or should I say Dane and who else?
