I have my S&W model 66 in the shop as the hammer and trigger need to be replaced.  While I was at the shop for another purpose, the smith said he would have to use new MIM parts.  I was not too unhappy, but I was already mourning that butter smooth trigger.  While we were BSing, he said he did have a carbon steel target hammer and trigger set.  I said put em on.  What a stroke of luck, wider hammer and trigger than before, and it will be carbon steel on a stainless gun, but that trigger should be awsome when he is done.  Should be a great target shooter, and I should still be able to carry it.

What are your thoughts?  MACHINISTINTX, ever done anything like this?

thanks

Why did the hammer and trigger need replacement? Other than some really extensive use or hack job 'smithing, neither should wear enough to justify replacement.

Using MIM parts isn't necessary because NOS parts can be found if a person wants to looks around a little. Also, ALL S&W's are equipped with carbon steel hammers and triggers. The stainless guns just had a "flash chrome" plating over those parts.

IIRC, the true target hammer is .500" wide and the target trigger is .400" wide. There were some semi target versions(I think this is what S&W uses now on the 686) that were .375" wide. The "service" hammer and trigger were both around .250" wide.

People bitch a lot about MIM parts, but the guns I have with MIM don't have bad triggers at all. One of them was at 4.5 pounds SA and ~13 pounds DA before I swapped the rebound spring....now it's more like 2.5/9. I still prefer the older case hardened parts though.

The trigger was worn out, it had been shot alot.  It was to the point you could push the hammer forward.  The gun smith is an old school police armorer with about 30 years on the job.  He is S&W trained / certified armorer and a pretty good guy.

The package said "target hammer and trigger" and are both really wide.  They are also case hardened colored.  I understand MIM has it's place in modern machinery, I am just glad I get to keep this revolver "ole timey"....LOL

I let you know when I get it back and shoot it.

Thanks Brother
