Hammer won?t drop after SAO conversion

[Blackhawk556]

Bought flat face trigger for my SP-01 w/safety and last night was along night

Bought the trigger from Armory Craft with the hope of converting to SAO. I removed the disconnect and broke my punch [emoji23]

The screw in the trigger is backed out and not hitting the frame for over travel

I am having trouble getting to the screw inside the frame that is attached to the trigger bar.

Is this screw not tight enough? Why doesn?t the hammer drop?

Hammer is in the cocked position. Can?t bring it down

Do a full tear down of the gun, take your time and find the issue.

Right off the bat, I would say your trigger is the issue, there is probably a set screw or something that is not allowing it to have the proper amount of motion to release the hammer.

On several of my single action CZ's if the set screw towards the top is too far set, it will not allow the hammer to drop.

Here is a detailed video breakdown of the gun.

I installed the CGW “Old Style “ trigger in my SP-01. The overtravel screws can affect reset . I tested mine at different positions before loctiting. Too far and the DA or SA would not reset after pulling the trigger.

I put the trigger bar in the freezer for a few hours and the the pin for the disconnector was a lot easier to remove. Did you mess with the sear?

Are you sure the hammer is all the way cocked back? My shadow 2 SA/DA converted to SAO sometimes has an issue because the screw in the trigger will move in, which doesnt allow the trigger to completely reset or hammer to fully cock. I have to back the screw completely out. Or manually cock the hammer all the way back.

What disconnector did you put in after taking out the stock one?
Did you cycle the slide to reset the disconnector and release control of the hammer from the disconnector to the sear?
If the hammer won't fall when you pull the trigger, you likely have the overtravel screw sticking TOO FAR out of the back of the trigger or something else limiting your trigger bar travel.
If you have an adjustable sear, your sear could be adjusted too tight to actually release the hammer.

Back out all the adjustment screws so they are not doing their jobs and then re-set them all in the proper order.
Too little pre-travel on the trigger shoe will keep the disconnector from disconnecting which keeps the hammer from being able to fall because the disconnector is not disconnecting when you cycle the slide.

I?m using the stock sear. I don?t think the stock one is adjustable, does anyone know?

I?ll try to back out the screws in the trigger I didn?t think to back out the reset screw

I?ll post back tonight

Before the boating accident, my home gunsmithing improvements all had the same issue; the nut behind the butt was always loose.

You said you removed the factory disconnector.
So that's why I asked what disconnector you are using.
Still no answer on that.
Also, what OTHER parts did you change out that you have not mentioned?

The trigger reset screw needs to be screwed further IN to the trigger so it's not sticking out as much.
Backing OUT the screw reduces the reset.
Screwing IN the screw increases the reset.
You likely have too little reset for the disconnector to reset.

Stock sear does not have an adjustment screw.
Only aftermarket sears have an adjustment screw and the adjustment screw is for safety engagement.

Maybe a new & improved Harbor Freight disconnector.

Here?s video of the issue

I pulled out both screws from the trigger as much as possible

From the reading I?ve done and the videos I see on you tube, you just remove the disconnector and dont replace it. I don?t have any in there.

As for the screws, I made sure they were not hitting that frame at all

Is the trigger you purchased the version that requires a short reset kit?

Cz customs has a similar trigger but recommends using it with their short reset kit.

Typically converting to SAO is a disconnector removal and sa/da hammer. but with the newer flat faced triggers a new disconnector is used to set pre and post travel. Then the set screws do the fine tuning

I know CGW used to offer a t3 disconnector. Not sure if they still offer it separately from their kits

It doesn?t say it requires the short reset kit

1.What?! You removed and did not replace the disconnector?! For clarity , did you reassemble the pistol with no disconnector installed? Your hammer/ trigger will not function with no disconnector

2. You want to adjust the trigger screws IN not out to get the trigger to reset.

There's your problem.

Your gun is not reconnecting the sear to the hammer when you release the trigger because you don't have a disconnector to reset the sear.

Put the disconnector back in.
The difference in DA/SA and SAO CZ type fire control groups is in the trigger.
The SAO trigger limits trigger bar forward travel so the trigger bar will not travel far enough forward to reconnect the trigger bar to the hammer in DA mode.
The SAO trigger basically gets rid of the DA option so all you have left is SA.
That's why its SAO.
