15-2 with trigger return problems. Trigger requires assistance forward after 18 or so rounds.
I:
Replaced the trigger return spring with a CZ/DW part.
Replaced the hand with a CZ/DW part.
Did the "Average Joe method".
Replaced the trigger return spring with a Wollf part.
Replaced the main spring with a Wollf #8. (also had ignition problems. Problem solved).
After each malfunction, removing the side plate reveals the return spring has fallen off the shelf of the trigger and has wedged between it and the hand. No wear is evident on the inside of the side plate where the hand travels. Hand too thin? Problem occurred with previous hand. Trigger shelf where spring contacts worn out?
Thanks in advance for your help.

Veeerrry interesting. You seem to be doing everything right. Did the Wolff springs lighten and smooth the action? Sometimes the hand gets jostled when you slide the sideplate in . After a number of rounds the spring can slip. Are you holding your upper lip right? It may be wear on the trigger but that is not anything I have heard of. If you need another trigger let me know. I have several extras. If the trigger return spring gets bent wrong when installing it might be prone to twisting off. I screwed up one once. Make sure the sideplate is in right AND the screws are snug. A screw could be stripped and be giving a little. Just guessing. Good luck.

Good advice Ole Dog. My first thought was a screw jarring loose. Honestly, the spring should be held in place by the hand if the trigger is not worn off, that would be a new one to me, and the side plate is fitted snugly and stays so.
I am surprised that CZ sent you a hand. They are usually adamant about fitting those type of parts, unless you are an gunsmith FFL. Follow the advise of the Ole Dog and don't use a lot of lube. DW's don't like a lot of it.

Any chance you could disassemble and take a close-up photo of the trigger shelf? I have just finished polishing/slicking up the triggers on my small and large framed Dans. If you took a close up photo it could reveal if the shelf is worn, but I can't imagine that being the problem unless someone took a dremel tool to the trigger at some point. Just doesn't seem like a part that could wear out from normal use even after 30 + years.
Just a trouble shoot and thinking out loud...when you reassemble the small tang on the opposite end of the trigger return spring needs to be captured under the post that the hammer fits onto. Are you are sure this part of the trigger return spring is in the correct position. Hope this makes sense I could take a photo and post to better help explain. give me some time.

That was my thought, that the spring wasn't seated all the way on the post

Thanks to all for the input. As time allows, I'm trying all advice. Work, kids, opening of trout season. But, not necessarily in that order. I will update.

Ole Dog, ese 927, PAbowhunter, and middlecalf,
I have read and tried each of your suggestions. Thank you.
The Wollf trigger return spring is in like new condition. I forgot to mention the sideplate screws were replaced when I replaced the hand and old spring. Still in great shape.
Side plate fits flush with surface of frame. I think the hand is an "over the counter" part. I Wiped off all excess lube.
I'm sure the short arm of the spring is in the correct position (care during installation and the long arm has considerable force). I tried to include photos in a post on this subject on Sunday, but nothing went through. I'll try to post pictures separately.
Side note: The old main spring was much shorter and weaker than the Wollf 8#. Got me thinking someone worked on the main spring and the trigger, and messed them up.
After the trigger starts to do the sticky trigger malfunction, if I back out the top sideplate screw to the point of no resistance, the trigger will return on its own for each additional shot. Opening the side plate reveals the spring arm is down on the hand pin (axle).

The second photo does appear to me to have a "shelf" where the return spring rests that has been ground down below the post that the hand fits onto and none of my triggers look like that. I am relatively new to this so get a 2nd opinion, but if that shelf is below the post I do think that is your problem and might be best to get a new trigger.

It doesn't look bad to me. It may be a bit worn. Try some light file action. Notice the shelf falls back to center a bit. Yours may be tailing away towards the outside.

PAbowhunter and SOWELA,
After reading your posts and seeing your photos, I think the rearmost portion of my trigger is definitely out of spec. Compared to DSCO1488 my trigger is missing a lot of material. The point of my shelf angles down and toward the hand. I'll try recreating a squared and pocketed point. If no success, time for a new trigger.
Thanks, MM

Here are two trigger hopefully you can see the amount of material/metal between the post that holds the hand and the shelf that allows the trigger return spring to ride/slide along.

No more sticky trigger.
I widened the shelf and created the concave I see in the photos. I used small files and a stone.
That's what it needed. No malfunctions after more than 200 dry fires (boy my hand was tired), 30 rounds of 38 Spl, and 20 rounds of mags (boy my face was smiling). This revolver rocks.
Thanks to all the DWF friends.

On behalf of everyone who helped (and I was none of them, I don't have those kind of skills), you are welcome. This topic defines what DWF is.
I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

Happy you got it up and running. Dan's are fun to take apart, inspect and slick up. The small frames are easy due to the side plate access, the large frames are kind of like Ruger gp100s or Redhawks in that you have to go in through the trigger assembly. Not hard just different.
