This seems to be sticky bolt on recently acquired DW44. The bolt functions just fine when shooting either SA or DA. But when closing the cylinder, the bolt won’t spring back up to engage the nearest stop notch. It will engage if you jiggle the trigger once or twice. Upon complete disassembly and cleaning, I couldn’t find any burrs on the bolt or the frame. Still sticks. I'm down to either stretching the spring (and getting new if that works) and/or polishing the area where the bolt and trigger interface. But I can wait for a more informed suggestion. Any thoughts out there? New spring set?
Thanks.

I have read your post several times and finally figured out which "bolt" you are talking about. Does your cylinder revolve past the first cylinder notch or does the bolt engage on the first one it comes to?
When I latch the cylinder on the guns I checked, it didn't always lock when closed, but locks on the first cylinder notch. If your bolt is not raising enough to catch the cylinder, I would look at the bolt to make sure it isn't bent, worn down or dragging in the frame. Use a pick to press the bolt to make sure it is "springy".
I can't think of anything else that might be causing the problem.
Good luck with it.

Thanks, Steve. No the bolt wouldn't spring back enough on its own to catch any notch. Without the trigger group installed it springs back OK but I can feel a little snag when the bolt is manually pushed down, almost like it's catching on a coil of the bolt spring where it goes into the crane. I did some very light 1500 wet/dry on the frame and some polishing on the bolt/trigger and now it works as long as the bolt lines up with a notch when I close it. I have a new spring set on order so I guess we'll see if that makes any difference. If not, I'll keep fiddling with it until I break something.
Thanks again for responding.

Let me admit I'm unfamiliar with the large frames up front. Because of this my "help" is based on the 15-2 mechanism where the bolt rides inside a cut in the trigger's upper end.
Is the axis pin (axle whatever) free or binding?
Random though, no more.

Random thoughts are good; keeps me thinking. If I remember correctly, all the Model 15s have a side plate that allows you to see all the parts and how they interact. The large frame DW's have this removable trigger guard group instead - similar to Ruger revolvers - so once you take it out to look inside the relevant parts are no longer connected. The bolt (cylinder stop) parts stay in the frame while the trigger, spring, hand, and connector (transfer bar) are removed as a unit. The bolt doesn't really have a connection or an axis point to the frame. Fully assembled, I can see the the bolt won't come all the way up and I can feel that something is binding, snagging, or sticking but it seems nearly impossible to pinpoint the problem. Arrrgggg!
But thanks for weighing in.

OK I found an exploded view of a large frame.
Have you tried something like "silver, or any other, contrasting magic marker". Paint the bolt with it, reassemble & cycle a few times. Remove & see where it scratched, wore off or was deposited, that you didn't put there! Then polish those areas with a fine (1600 or 3200) wet & dry, repeating till it starts working reliably, no more.
You can remove any residue with alcohol when you're done.

I'll try that tomorrow. I thought of trying to using carbon paper (yep, I still have some) but couldn't find a way to make it work. Never thought of a using a marker. Silly me. There are about six possible areas on the bolt, so that should be very revealing. Afterwords, alcohol will be liberally applied to the firearm and me.
I appreciate the suggestion.

All of the contact points have been polished and I finally received and installed new springs, nothing really improved. I did discover, with a big magnifying glass, that the bolt has been cutting a groove in the frame and that appears to be where it's hanging up. Gonna use this frame for parts rather than futz with it.
The frame pins are what the lockwork are located on and turn on. On small frames they look like rivets on the right side. I can't remember off hand where they are on large frames. Find them and make sure they are fully seated. Use a rubber mallet to tap them. If they have backed out even a little bit all kinds of strange sh-t can happen. It may not be the problem but it can't hurt and may help.
