Hi all,
I have a 715 that I recenlty acquired and the trigger/cylinder seems to bind up occasioanally. I have read that it could barrel spacing but I have it set pretty loose in my opinion. Using .006 guage, I first set the space nice and tight where I could insert the gauge easily but with noticable resistence. This is when I first noticed the tigger lockup. So I loosened the space up a bit where the guage can slide in and out with very little resistence. I still have the lockup but not as frequent. What is the 'rule of thumb' when setting the space?
Thanks,
Brett

Brett:
1) Setting barrel gap, make sure to check all the chambers individually, there can be inconsistencies in the flatness of the cylinder front. You can easily go as tight as .003 on the tightest chamber.
2) Try loosening/tightening the grip screw slightly while dry firing. Grip screw length, and how far it screws in to the frame can affect trigger function. Some grip screws came with a small washer at the head of the screw, if that is missing the grip screw can go too deeply into the frame. There are two length grip screws, for full size and compact grips.
3) Pull the sideplate off and thoroughly degrease/clean the working parts, and consider a spring change.
Work your way through these in order, you should fix this problem fairly easily.
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.

I can't add anything to Steve's advice but wanted to give you a link to the some disassembly instructions...

My 732 exhibited similar issues and removing the fuzzy from the insides resolved it.
Good Luck. Let us know how it goes...

You may also want to make sure your extractor rod isn't unscrewing itself from the extractor star. One of my guns did that a couple times & it will lock up the cylinder rotation, when it happens.

Hi All,
OK I am back with an update. Thank you for all your suggestions. Unfortunately the cylinder is still locking although not nearly as frequent now. It only seems to lock up when firing the revolver rapidly.
Here is what I have done from a troubleshooting stand point:
1: Removed the barrel to eliminate incorrect spacing issues.
2: Disassemled the revolver, degreased, cleaned and re-lubed inner workings.
3. Replaced the mainspring with a new 8lbs Wollff mainspring and a new Wolff Trigger Return Spring.
4. Replaced the grip screw with a new factory grip screw.
As mentioned, it is still locking up but only if the action is worked in a rapid fire manner (probably every 10th or 15th shot.) Could this periodic locking up be due to a worn bolt or worn cylinder (the grooves on the outside of the cylinder that the bolt goes into?)
Is this something to be concerned with?

If it's only doing it after every 10th or 15th shot & only when rapid firing, I would worry about it if it was my gun. Heck, even auto's will often have a similar malfunction when put to that same test.
Most of my shooting is in single action, and when I do shoot double action, it's rarely more than 3 or 4 rounds before I decide I'm needlessly wasting lead. 😛

That sounds like a trigger return issue to me. On a DW the trigger must FULLY return (and with emphasis) to completely reset the internals to proper location. Sometimes that's why a simple lube job has such amazing results--everything resets back to where it is supposed to.
Sounds like you finger is wearing out after 10 to 15 rounds ... 😉

I like for every gun to function correctly, just on general principle. I require perfect function in a defensive gun, and none of my DW's are primary defensive guns. If you can shoot 50-100 rounds of recreational shooting without a problem, and it's not a self defense gun, probably no harm-no foul.
Sounds like something in the internals is worn, and just doesn't stand up to rapid fire. if that's how you want to shoot it, get it fixed. If it's otherwise functional and accurate, maybe just enjoy it as is.

OK, great advice from all. Thank you.
It is not one of my "combat" weapons so I will take you all's advice and not worry about the periodic lockups as I will probably shoot it liesurely at the range anyway. Tee real problem is that I have grown fond of this Stainless revolver and its unique flexibility and want it to be perfect (I am sure you all can understand.)
Concerning the trigger return and tired finger, I though about this and suspected that my self, so I decided to run a similar test on an old beater Colt Trooper that I have. Unfortunatley after numerous tests, I cannot get the Colt to lock up. So I suspect the worn parts theory and given the mild nature of the issue, I will just live with it until I get an opportunity to take it to a gunsmith one day.
I do appreciate the input and advice though. I have learned a lot and I have a nice, healthier Dan Wesson as a result.
Thank you all.

Brett, check on the Parts and Service Forum, there is a pretty recent post on a gunmith that seems to be pretty knowledgeable about DW's
