I have a question regarding my newly acquired Model 66-2 regarding the hammer nose and a channel in the frame made as to facilitate clearing it. It seems there is wear in this channel. The hammer nose clears it, but if I tilt it all the way up in the hammer, then it will make contact with the channel, but is pushed down and clears it. Is wear here normal? Should I worry about the hammer nose breaking? The hammer nose has no sign of wear, but this channel does and is quite thin at the begining.

My old, well used, 66 from 1972 displays the same contact between hammer nose and frame. I have seen this with several other S&W revolvers, but have not personally experienced any damage to the hammer nose...

This is good to know, thank you. I've looked up as many pictures of the Model 66-2 as I could, and saw the channel in then, but didn't know if the hammer nose can make contact. I've had a Model 66 no dash years ago but didn't recall this on that revolver.
 
IMHO, that groove is machined into the frame. I went to look at the K frame .357's that I have and they all have the groove, or notch.Some are a little more pronounced than others but they're there.
I only checked the mdl 66's and 19's.
Not that my opinion matters but the fact that there are other guns that have the same thing should put your mind to rest.
I'll let someone more knowledgeable opine as to WHY they're there.

I think it was a measure to keep from breaking hammer noses before, or in addition to, the spring to hold the hammer nose in the down position. Just a guess on my part.
