I have a S&W model 629, I went out shootin today and came home and cleaned it, I did unscrew the ejector rod and removed the star to clean( have done this numerous times n the past) and reinstalled, I did not notice anthing out of the norm, it all went back together with ease, I closed the cylinder and now it wont open back up, I pushed on the side of the cylinder with some force but didnt wont to go too much not wanting to do any damage or bend anything, it seems like the pin that latches the cylinder in place isnt getting the clearance it needs to open up ...what the heck do I do??!??!!?
