1066 and 4506 hammer swap

[A320graham]

I would like to put a spurred hammer on my 1066.
I think it is called spurred?
And have found the 4506 hammer should fit the 1066,
both DA/SA etc.

Then I find the part # in the S&W parts list for 4506 and 1066 is the same for both guns 26223.

But the S&W tech says that part # will not fit the 1066??
Any member tried this MOD did it work?
Many Thanks.

The 4506 spurred hammer fits the 10XX series as well. I've replaced them many times on agency weapons. The only issue we followed was to replace "like-kind," meaning flash chromed bobbed hammers were replaced by flash chromed spurred and MIM bobbed by MIM spurred.

That being said, none though it would make a difference to replace flash chromed with MIM....

1066s and 4516s were almost universally set up with spurred hammers after we figured out how easy it was.

Yes exactly what I thought but the S&W tech knows best what!
Well perhaps not.
Trouble is I just ordered some springs for my 1066 +$7 for shipping.
With a new order they will charge me shipping again "cunning stunts" that they are.

It's the same hammer regardless of what they say. The "hammer assembly" number can be different depending on if your 1066 has a "short" or a "long" hammer stirrup....perhaps that's what he's talking about. The easy way to make the whole problem go away is to order just the hammer from MidwayUSA or S&W (if you really want to) and just use the hammer stirrup pin and hammer stirrup on from your bobbed hammer.

Your 1066 probably has a flash chromed hammer, and I'd bet S&W will sell you MIM hammer. Maybe you should look at MidwayUSA and see if it's in stock there. If it is, it'll probably be an assembly and you'll need to change out the stirrups to fit what your particular pistol uses. If you end up with a MIM hammer, MidwayUSA also sells the MIM black trigger which will match up...it matching is something important to you.

The 1066s, and early 4566s, are the only S&W 3rd Gens I've seen that have different stirrup lengths...I'm sure there are more and perhaps more experienced people will speak up. The easiest thing to do is just use the existing stirrup.

Any questions you have should also me posted in the Semi-Automatic Pistol section....you'll probably get more attention than in the Gunsmithing section.

Thanks for all the replies.
Order went in yesterday let us see what happens.
Did not know which section to put it in so went for the smithing section.

Here she is.
Put Trijicon's on as well!
I get hammer bite not bad but I can see why they went spurless.
Is the beaver tail on a 45 bigger or should I say longer than the 10?
To stop the bite.
