Update. Thought the innards may be dry, so at the range applied a small bit of lube up under the main spring. That was a mistake! Now I had almost no double action! Shot fine in single and the next shot was also fine in DA. Fired of about 30 rounds in SA just because it is fun and thought things might work their way in. Nope. At home took off the grips, removed the cylinder and gently took off the side plate. Everything looked fine to me as I have never seen the inside of a revolver before. Sprayed some Gunk-out to give things a rinse, and let it sit and dry. Then a tiny bit of Rem Oil. Put the cylinder back on to cycle and to see how everything moves. All was good in DA with a quick release of the trigger. Slower release ok too, Good, an improvement. Very slow release and the problem showed re-appeared. Seems the sear would not reposition correctly by popping back out over the trigger. Perhaps it is a weak sear spring? Checked my 617, 686 and 929, and none have the issue. Also, when resetting the trigger with those three guns there are TWO distinct clicks. With the 625 there are three, with the 2nd and 3rd clicks being very close together. I do believe this gun will be heading back to the factory for a fix. I will take it to the range a couple more time before that. It is a great shooter. Please jump in if you have any helpful hints.
