Hello!
This is my first post on the forum, but I used your knowledge many times before- which I really appreciate.
I have 2 Dan Wesson revolvers and I love them for their accouracy. Unfortunately I have some issues with both. Both have issues with cylinders:
1) model 715 .357 mag: the cylinder is not blocked properly. When I push cylinder from right to left, with 1 finger and not much force I am able to open cylinder. Moreover second issue is that I can easly rotate the cylinder in opposite site that it should rotate.
2) old model 15 .357 mag: the cylinder is not blocked properly. When I push cylinder from right to left, with 1 finger and not much force I am able to open cylinder. This piece also does not fire all primers in double action, but for that I know I have to replace main spring in handle.
I kindly ask you to point which parts should I buy and replace. Unfortunately, I m not from USA, but I can import parts from USA easly (ebay, other stores). I would appreciate most the exact names of parts or links.
To easly show what are the issues, I uploaded videos of both my guns:

Check the mating face on the cylinder latch.
Its the inner "rib" on the top face of the latch. Also give a thorough deep clean. Crud can get in the recess for the spring limiting its power & length of movement.
Mine developed a burr & so couldn't drop into the cut in the frame fully.

I didn't know how to use it.”

Thank you for advise. I m on vacation now and I will be back to topic after that, in 2 weeks, cause I have to finally solve that for both guns.
I will keep you all updated in this topic.

The first thing to do is a thorough cleaning using the Average Joe method on the forum. Then my next move would be new springs for both the latch and the bolt.
Technically, the glass is always full; half liquid, half air....

Exactly. ^^^
Rowan45, those guns are begging to be blown apart for a good scrubbing.
I have bought a couple guns on GB in years past (my 7445 comes to mind), where they looked good in the auction photos, then once they were here & in my hand, I was like holy 'chit, this thing is freakin' filthy! 
The cylinder on the 7445 did not want to latch well at all, turned really tight & the barrel fouling was terrible. I immediately blew each of them apart for a well deserved good 'ol scrubbing. They have been very happy guns since then. 
And that was what...12 ~ 14 years ago? They are still happy guns.

Hello All,
I m back from my vacation. Thank you all for replies 🙂
So I did some SPA for the old 15 model. You all were right, it was dirty as hell, I had to scrub it for a long time with brass brush and gun cleaner. Here you can check some before/after pics:
This part looks a bit worn, but the top seems to be still sharp:
This photo was shoot before cleaning. I couldn't find the U-shape spring here (red arrow). I saw on dissasembling videos that there is such spring, but I dont have that in my piece:
Could somebody please advise me if these dimensions and appearance of the main spring are OK or should I buy brand new spring? To solve issues with Double Action shooting.
I would be very thankful if you could tell me what are the names of springs that I need to buy and even better, if you have links to them.
I wanted to do similar troubleshooting for second gun. But I have issue with 715 model- I cant open latch- I have 2 sets of allen keys, in cals and in mm, but nothing fits. The 1,5mm is too large and when I tried cals allen keys, the smallest is too small and the bigger is too big. Do you maybe know what is the correct key size? Probably I will also need some new springs there :/
