If not you may have to remove the action from the stock and then remove the trigger.
My 38 did this once when I was transitioning the safety or something.
I played some serious HELL trying to get it undone.
It's one of the oldest guns I own and one that I have owned for DECADES....never had a problem with it and then one day..."BOIK" it was stuck.
Has not happened since, either.
I do not exactly recall HOW I got it unstuck but I do believe I loosened or removed the action screws and, with the action out of the stock, I jiggled stuff around, held the trigger down, etc and all of the sudden..."un...BOIK" and it was ok again.
