6906 hammer

[Heymatt]

Got a question that came up that needs an answer.
Trading parts with Guzzi and I have two hammers. Both marked 6906, but one appears to have been shaved on one side.
Neither one of us knew the answer.
Can anyone shed some light on why that would be done?

Heymatt, the top hammer appears to be a 2nd gen hammer with the half-cock notch filed off.

Top one is marked 6906. Which is what’s throwing me. Looks like the hump was ground off for a second gen maybe?

S&W didn't like to waste things.

The half-cock notch hammer caught a lot of flack in the popular gun press of the day primarily because of the "hitch" it created in the double action trigger pull and secondarily because it was redundant with the addition of the firing pin safety.

The 6906 was a hot seller and S&W probably chose to "update" some left over 2nd gen hammers and re-mark them for use in 3rd gen pistols.

So, no issue with function on either one in a 6906?

Both should work just fine.

Awesome!
As always, thanks again John for sharing your knowledge!

Always glad to help.

I have a hammer shaved exactly like that. It is VERY smooth, and works just fine. I guessed someone shaved it to take out the half cock notch, which makes the trigger have a heck of a hitch in it's pull.

Seen some of those where the flash chrome finish and laser etching is completely intact. That tells me the radius or half cock notch above the full cock relief was obviously ground off the unfinished part before flash chrome & marking. I have two of those here with identical grind profiles, one is completely chromed and the other is raw at the ground flat. One ground before chrome and one after chrome.

Anyway makes for a nice smooth DA as the sear never touches the hammer during DA. Only after that first shot does the sear ride across the full cock relief and engage the full cock notch.
