Converting a P229 DAO to DA/SA. Trigger bar? Login/Join

Sig P229.40:

I was told when I bought the pistol maybe 2 years ago that it was a DAO. But some in the classified section of the forum say it's more than likely a DAK. It really doesn't matter to me which it is because I wanted to convert it to SA/DA after inadvertently breaking the hammer upon reassembly after having the frame cerakoted. I put it all back together and pulled the trigger. I didn't realize it was in a bind when I pulled the trigger and it broke a little tang or something off of the hammer.

I ordered the parts needed for the conversion to DA/SA. I did not order a new trigger bar but now thinking I probably should have. I may also need to order a different hammer strut but not sure. I'm relying on you guys to tell me what I need.

The problem I'm having is that the trigger bar is making absolutely no contact with the new hammer. Included are images below of the original hammer as well as the new DA/SA replacement hammer, and others. Thanks for any responses.

Spazz,

That hammer looks like a DAK hammer instead of DAO hammer because there is no spur on it. DAO hammers have a slight spur on them.

Matrix Precision (a.k.a. Revenant Arms) sells a kit to convert DAK to DA/SA. You wil need to buy the whole kit less any parts you have already purchased.

The second photo shows where the spur is broken off. I didn't know what it was called. I called it a Tang in the post above.

I think you are referring to the bottom of the hammer. I'm referring to the top.

This is what a DAO hammer looks like:

Sig Sauer P Series Bobbed Hammer, DAO

And this is what a DAK hammer looks like:

Sig Sauer P Series Hammer, DAK

You definitely have a DAK hammer. You need all the parts necessary to convert a DAK pistol to a DA/SA pistol. As you can see from what Greymann posted, it is a fairly extensive list.

I found a photo online that shows intact the part of my DAK hammer that broke off.

Yes, you have a DAK hammer with the stud broken off. That stud permits pulling the trigger when using the short trigger reset of the DAK system. I believe, but don’t know absolutely certain, that even with the stud missing the gun could be fired if the trigger is allowed to reset fully forward. If you would be interested in selling the DAK hammer with the broken stud, I would be interested for my research purposes.

As for the list of parts necessary to convert from DAK to DA/SA, a new sear is not required. The sears used in DAK pistols can be used in DA/SA pistols. The reverse is not always true if one has a sear dating from before the introduction of the DAK line.

In addition, DAK-only grip plates are in actuality virtually unknown. DAK pistols were usually supplied with grip plates that are usable with a decocker. A photo of the left side plate would confirm that.

And FWIW, some SIG Classic line pistol hammers (except for P239, not pictured):




Left to right: DA/SA, standard; DA/SA, “sport”; double action only, with spur; DAO, “bobbed”; DAK
