 Often when I pull the trigger slowly in DA, as soon as the cylinder locks up the hammer stops. It takes a enormous amount of pressure to get beyond the hitch. Enough that I don't want to force it kind of pressure. If I pull the trigger quickly it cycles normally. It does this with cylinder open or closed and it doesn't do it every time. SA is fine. I've read the average joe's tune up but what should I be looking for?

Thanks, but the first thing I tried was removing the grip screw and it made no difference. My wording is probably incorrect, but it feels like some part of the DA mechanism is hanging up/not allowing the hammer to complete it's last part of it's travel and drop. I haven't had the gun completely apart yet but there are a few places like this that are scratched from wear. I think I could handle the average Joe tune up I watched although I haven't had the guts yet to go that far.

Rarely will anything 'hang up' in a revolver unless something broke.  It's usually a case of improperly placed springs, other parts not installed correctly, cleaning, or loose side plate screws. Go ahead and knock out the AJT- if you get stuck there's folks on here to help you out.

First my thanks to shootist for AJT thread. Total disassembly was much easier than I thought it would be. My trigger issue may be caused by some excessive wear/rubbing on the right side at the bottom of the hammer. I found the spot on the frame it appears to be rubbing against. I dragged a fine stone across roughest part of the hammer a couple times to smooth the edge a little and then used Mothers mag polish to slick it up. The hammer was pretty much how you see it now since I barely touched it with the stone. I polished the top of the machining marks on the frame in the area the hammer travels and gave it a deep cleaning. I put a Wolff "competition" trigger return spring in also. It's improved some but the issue is still there and I suspect the wear on the bottom of the hammer is causing it. If I pull DA very slowly the issue is obvious. If I pull DA more quickly it's not very noticeable most times. Is the hammer a drop in part or does it need to be fitted? I was afraid to get too aggressive with stoning the hammer to smooth up the worn/gauged spot. Do you think I could stone that edge smoother or would it lead to problems?IMG_0306.JPGImage Enlarger

It's a drop-in part. I would stone it and smooth it til it cures the problem. Note that it may not be the only place needing smoothing.

Make sure the frame pins are fully seated. Very easy to tap them fully in if they are not.

Thanks, That makes sense if the hammer pivot pin wasn't seated properly it could wobble enough to allow the hammer to get out of the proper position. Ignore my reply on "spare parts" thread. I didn't know you replied here. Thanks, Ole Dog

The pins were seated. I found a trigger and hammer less worn than mine for $40 so I installed them and still have the same issue. I removed the mainspring and gave it all a good cleaning and polished the mainspring rod/strut with Mothers to smooth it up. I've run out of ideas for the time being.

Have you replaced any of the springs?  Still sounds like a spring issue to me...

Could be. I replaced the trigger return spring. The mainspring & strut(rod) were taken out and cleaned up as well as the hole it sits in. It seems to function smoothly. There's so few parts inside these DWs it doesn't seem it should be difficult to figure out. Could it be the hand and star not interacting properly? Looking down the barrel and through the cylinder, all chambers look to be centered. Is the screw that holds the ball bearing the star snaps into supposed to be seated all the way in or made to be adjustable? This is my first DW so pardon any stupid questions.

Ron is probably right. Check the strut spring. It could be broken of missing. The hammer has the strut attached to it. It swings in and compress the strut Pin on a spring. If the spring is broken or lost it may make the double action not work

If the spring is broken or lost it may make the double action not work. The trigger return spring may be falling off the ledge when you put the side plate on. You have to hold your upper lip just right to get it right.

I guess I should have said strut spring instead of mainspring to make myself more clear in post #11. I took the spring and strut out and inspected them. I thoroughly cleaned both and polished the strut. I cleaned the hole the strut and spring seats in. After reinstalling the strut spring and hammer only, the hammer pulled back and forward smoothly using my finger. The trigger return spring seems to be staying on the "ledge" where it belongs. The DA does work but not smoothly if the trigger is pulled slowly. SA is fine. It's not a big deal but would be nice to have a good, consistent DA trigger. It feels like something is interfering with the last of the hammer travel at or just before lockup.

I would also check the detent ball and spring. If it is too loose, it will cause problems. You have to remove the hammer to adjust the retention screw. The screw should be roughly level with the frame. 

Sounds like you are on the way to finding your problem. Keep going! cool
