I had the good fortune to score a 2010 production P232 that was in parts in a bag.
Once back together I figured out the failure to reset into single action was because of a DAO hammer that was installed.

What was weird was the hammer reset spring was trimmed so it wouldn’t properly engage and the decocking lever was installed.

Did Sig deliver the P232 with a DAO and the lever instead of the stud to retain the sear?
Does anyone know the PN for the hammer?

A new hammer and hammer reset spring and I’m back in action. Hopefully selling the DAO hammer will offset or cover the replacement parts.

The late production 232 is a nice shooter and easy to carry.

I’m not sure from your post if you’re seeking a DA/SA hammer or already have a source identified. If the former, Numrich lists them:

A couple of my old armorer’s manuals have sections on the P232, but no mention of DAO models; they also do not list part numbers except to identify schematic parts. My most recent manual pertaining to Classic line pistols does not list the P232.

When I asked the AI Copilot about DAO P232s, the response was that they were very rare variations, and that they did not have the decocking lever. Although such answers are not always correct, the lack of a decocking lever is true of other DAO Classic line pistols, so I can only wonder whether your bag of parts included the decocking lever because the gun had it before it was converted to DAO.

I have seen DAO P232's pop up on GunBroker from time to time. I do not believe they had decocking levers.

I replaced the entire FCG with NOS parts squirreled away and bought new.
- hammer
- sear
- sear spring
- trigger bar
- trigger bar return spring

And the recoil spring with with a factory NOS spring.
The damaged hammer return spring had to be a matrix part and it’s inbound.

Between the clipped hammer return spring and incorrect pairing of the DAO hammer and decocking lever I figured it was prudent and cheap insurance. It’s strange it shipped as DAO and ended up with a decocking lever. Especially due to the lack of wear on the blue slide. It definitely wasn’t carried a lot.
