I stripped my 629 44 mag, to clean and did some polishing. I thought i had everything back together. Is the hand that rotates the cylinder supposed to float? I can shake the gun and here it move, if i tilt gun with barrel pointing up the hand wont grab cylinder, if i rotate gun with barrel pointing down hand will then grab cylinder and rotate it. I triple checked everything both of the location pins on the hand are in the two holes in the trigger assembly. Im confused. thanks, alot.
