Hi, new member here …

I purchased a 744VH (4”, 6”, 8”, 10”) new back in the late 1980’s and put maybe 1000 rounds through it. Great gun… just not practical for what I needed, so it’s been in the back of the safe and taken out just to clean over these many years. But my son has a renewed interest in target practice, so I took it out to go over it in order to gift it to him. While cleaning after putting another 50 rounds through it (did I mention this is a great gun?) I popped the cylinder out by pushing on the back side, without touching the latch! The spring and latch seem to be functioning properly, so I started looking to see what the problem may be. What I found was the latch is a trapezoid shape, while the notch in the frame is a half moon so it only catches on the points of the trapezoid. Has anyone noticed this on their DW’s? Do they make half moon latches? This seems very out of place… I’ve never had it open before while shooting nor while cleaning but all of my other brand revolvers lock up tight. Any information would be appreciated.

They're all that same shape- even the large 445 Super magnum.  I suspect there's some dried crud in the spring or channels, preventing full travel upward. The first things is a disassembly and cleaning.  The spring could be weak and need replacing as well, but I suspect dried oil to be the culprit. 

A previous discussion HERE.

Technically, the glass is always full; half liquid, half air....
