6906 with hammer for 3904 /5904

[Psycshrink]

Im having a much needed action job on my 6906 which had a trigger pull over 14 pounds and the internals were rough. He said the hammer was marked only for 3904/ 5906. Anyone hear of this substitution? It must have been done at the factory. It works fine no issues at all.

I do believe that when the Serious Big Dogs get here, they can confirm my initial impression that those hammers swap around like ... like ... I dunno, what are the kids toys that swap parts around these days? So long as the strut matches the frame length, I've had spurs and no-spurs on all sorts of 3rd Gens with no problems.

Oh, and Forged-to-Forged or MIM-to-MIM on 'em. No mixing allowed.

But.....

I could be wrong at which point the Big Dogs Who Know Stuff will hurt me. Severely. When they find out.

I had my smith install a 5906 hammer on my 3913. Took less than 5 minutes, & I really love the gun that way now. Both hammers are stainless. GARY

Why would 'no mixing allowed' be an issue? I have them mixed on two pistols, I have not noticed any issues.

I've never heard of a hammer marked for those 2 models, normally the older forged 5906 hammers I've seen are marked for other stainless TDA models (3904 is blued). Grabbed a pic off the internet as an example.

Is it possible that your guy misread 3906 as 3904, and just mentioned those two model numbers out of the whole bunch?

The 6906 came standard with a spur-less/bobbed hammer, so if yours has a spurred hammer, then they would have substituted one from the 5906 line, which simply doesn't list the bobbed hammer models as an option.

No I saw the hammer and it was slightly modified to make it fit. I have no problems with it so we just left it in. If its not broke dont fix it.

Hammer interchangeability

Without pouring gasoline on the issue of MIM/non-MIM mixing of parts, I've seen several models listed on some of the hammers I've had pass through my parts bin over the past few years. I have yet to see an overall rhyme or reason beyond the obvious... Here's a pic from what I pulled out this morning. Interestingly enough, three of the four were "bobbed" versions: MIM at the top of the pic, then non-serrated, and finally serrated "machined" versions.
Looking at this week's posts with respect to hammers, it seems we could almost come up with a "Bear" thread on this subject alone... Interesting stuff, indeed!

You would need to keep in mind that in the early 3rd gen days, the only pistols made were 3906/5906/6906, 3904/5904/6904 and 4506. The only blued spurred hammer models were 3904/5904 - therefore an early blued hammer would be marked as such.

I agree, 3904/5904 would not be surprising, but the OP is talking about a hammer marked for 3904/5906, which is a blued & a stainless model listed together on the same hammer. That's what doesn't make sense to me, normally it seems to be divided by blued-stainless and bobbed-spurred.

Ah, he says 5904 in title and 5906 in body. That would be the source of confusion right there!

That would seem to be it, good eye jsbethel!

I saw the hammer myself and those numbers along with only were stamped on it. It works fine
