Greetings all, I am a brand new member and am hoping to get some ideas or advice about an issue I am having with my S&W Model 28 no dash Highway Patrolman revolver: When I attempt to slowly pull the trigger in DA mode, or slowly thumb cock, I get about a 1/4in of movement and then solid lock. Trigger/hammer will no longer move to the rear. If I let hammer back down from this position I can usually cock or pull trigger normally. If I cock the piece or pull trigger in a normal speed I may or my not get a smooth trigger pull or I will feel a catch in the action. However at other times I will get completely normal, smooth trigger/hammer movement and smooth action regardless of speed doing it - and then at some point the problem will return. I have noticed obvious shiny wear on the left side of the trigger where it rotates up into the frame and believe this is totally related. S&W gave me no suggestions as to problem just to send in for inspection so thought I would pick some brains here before going that route. Although my knowledge of timing issues is not the most thorough - the revolver cylinder locks up tight every time and there is no endshake.
