722. Range today. Locked up tight. Trigger locked back. Hammer moves. Cylinder locked with two live rounds left. Somehow I was able to unlatch the cylinder and exact cartridges, but back in frame, still seized up. Definitely internal. Could not get sideplate off.
What it was doing before this was randomly the cylinder would not advance i either SA or DA. If I rotated the cylinder slightly it would advance and fire until the next malfunction. there were also light strikes in the rimfire cartridges. Rotating around a 2nd time DA got them to fire. Gave it back to my wife and same issues.
Since my wife was shooting this one, is it alright to blame her?

Wow that cylinder has really moved rearward in the frame!

Wonder if the cylinder centering ball screw backed out and it and the spring fell into the works...

I'm wondering the same thing. That would account for the cyl position and jam up the works.

So, what internal parts might need to be replaced?
Two members are liquidating parts, so I might as well grab whatever I might possibly need. I did a first attempt to remove the side-plate. I may try again this week

I'd get an alignment ball, spring and retaining screw as a bare minimum.

With the cylinder that far rearwards the bolt may be hanging up on the chamber flutes instead of its notches! Perhaps even unable to "drop" because it isn't aligned with either?
What happens if you push it forward manually while trying to cycle?

Before it locked up, it would hang on both DA/SA. I could manually advance the cylinder until it locked into place.

The answers will not be found until that side plate is removed. You could try to get some kroil or other penetrating fluid to soak in around the screw heads for a couple of days then use the best Allen wrench you have. To ensure the best fit possible I have occasionally ground off the last 1/16 of the wrench to get a “fresh” bite. This will hopefully keep the screw head from rounding out. All you can do then is to just go for it; if the screw snaps, it snaps, then it’s easy out time, but at least you can finally see what is going on in there.

The two screws came out fine.....are there more I don't see? It's the sideplate I cannot remove.

Oh, I see. Treat it like you would a Smith or Colt’s side plate; tap the grip stud with either the wood or plastic handle of a screwdriver and let it vibrate loose. Tap fairly hard and rapidly. If it still doesn’t budge you will have little choice but to pry as gently as possible behind the hammer along with some vigorous tapping. Pad your prying tool as well as you can to avoid any marring. That’s about all I can think of to try. Good luck!

Here's the Problem: In the picture you'll notice the trigger detached from the arm that locks the cylinder in place. This detachment was the cause of the malfunctions before I ever opened her up. she was shooting then the trigger would not return. Although I have put her back together, the problem still exists. A new problem seems to be is my DA is not a SA. I got it to DA cycle once. WTH? I think I am now in the advanced course. Also the cylinder has about 1/4" of play that I do not recall being there 6 months ago when the malfunction happened. Side plate does not want to fit back in either. I thing the cylinder is preventing it from fitting back in? It was a pain to get out.....took 5 months to try again. Help! please

Wow, that’s an interesting photo. The thing that jumps out to me the most is the fact that the ratchet star is nowhere close to being in its proper place, and the cylinder is closed! Exactly what is the 1/4” play in the cylinder that you’re referring to? I’ve included a photo of my 15-2 with the side plate removed and everything in place. Hope this helps.

The ejector star is not seated into the recess of the cylinder, judging from the photo, and binding everything up IMO. I'd start by lifting the trigger out and then try to get the cylinder lock disengaged from the cylinder. Then, take the little horseshoe clip that retains the yoke out and try to open the cylinder. Once the cylinder is out you can inspect the ejector & cylinder. Basically I'd do a complete disassembly except maybe the hammer and mainspring. This is just what I'd do but the key to your problem seems to be that ejector star out of place. Good luck

With the plate off, and cylinder open, the cylinder will slide 1/4-1/2" back on the shaft towards the hammer. Is the ratchet star also the ejector star? Comments have been made how far back the cylinder is. I would guess 0.004 in clearance between the cylinder face and the back plate/blast shield. Although I have it back together, and it appears to be functional, I never determined the cause of the original malfunction. Testing today.

Yes, the ratchet is also the ejector star, and with the side plate removed you can slide the cylinder off the shaft completely once you unscrew the ejector rod. What I still can’t get my head around is that the photo you posted should be impossible to take. I’ve included a couple of photos that show how the ejector should fit into the rear of the cylinder. You will notice the tiny roll pin that locates the ejector in proper alignment. Are any of these parts missing? I simply can’t duplicate what is showing in your photo.

Also, looking back at the photo in your first post there seems to be something odd about the collar on the front of the cylinder. I have no experience with a 722, but I’ve never seen anything like that on any of my DWs. Can you give us a photo of that end of the cylinder swung out?
