Model 36 Strange Issue

[jimmyj]

Firing a Blued 2" Model 36 at the range with factory 158 grain standard loads using double action . When I started on the second five rounds when suddenly only the cylinder would rotate without the hammer moving.
Then the action froze-trigger, cylinder latch, and cylinder would not move.
At home I took the sideplate off and everything appeared normal except the safety bar seen to be loose out of its groove. Had a really difficult job trying to re-install the safety bar correctly for the sideplate to be re-installed.
Finally was successful and the action is back to normal.
This revolver is in new condition.

First time this issue has happened with a S&W Revolver.

Opinions ??

Vintage pre-lock Smiths are available at good prices.

Jimmy, is the M36 you had issues with new with an IL or a vintage model - you did not state. All you stated was that it was in "new condition" It might help to know. One can have an old vintage gun in new condition, that's why I am asking.

The Model 36 is vintage pre-lock

Sounds like maybe a bit of dirt got into the DA sear on the hammer when the cyl. would turn, but not cock the hammer. If the sear was stuck in the back position, the trigger wouldn't be able to reach it.

Then it sounds like whatever it was migrated to somewhere else to lock up the action. A good cleaning wouldn't hurt it.

The best way to keep the hammer block in place while putting the sideplate back on is to put the hammer block on the pin of the rebound slide, then roll the gun up on the barrel and top strap with the grip about 30 degrees off the bench and install the sideplate. What this does is keep the hammer block in place with gravity till you get the sideplate seated, then it holds the hammer block. Then you can lay the gun back down on the bench and put in the sideplate screws.

I think Protocol Design is in the right track. Check out the operation of the Sear next time you pop off the side plate.

I put the hammer block in its upper most position and then slide the side plate on with an upward angled rear. Decrease the angle of the rear of the side plate as you push it over the hammer block and downward. Press the side plate down evenly and make sure it's fully seated in all corners. It's much more difficult to explain than to actually do it.
