Help! A new 637 in lockup!
Picked up a new 637. Dry firing in DA mode today, it locked up. The cylinder will not disengage, nor will it cycle. The cylinder latch is also immobile. There's about a quarter inch of play in the trigger but it doesn't engage at all. The hammer will not budge from the down position. Definitely tossing it back to SW for inspection and repair. Anyone care to venture a guess as to what these symptoms may indicate?
