Hey all. First post and it's about a new 629-6 I bought new this morning. Brought the gun home and loaded up a cylinder to test fire it. First thing I noticed was that the rounds didn't "plop" into the cylinder. They had to be pushed with minimal force. This isn't really even the real issue this post will point out, but rather something I noticed right off. I expected the cylinders to be more smooth and not offer any resistance whatsoever to the rounds simply dropping in. The real issue came in test firing. Fired 4 rounds single action with no issues. Round 5 I fired double action. It fired, went to fire round 6 and the gun locked up. The hammer was back along with the trigger and would not release no matter what I tried to do. Cylinder did open, which in my experience is not something that should be possible with a cocked revolver. Looking around at every component I could, pressing the cylinder stop in showed me that it would stay down and not return as if it had no spring pressure. closed and opened the cylinder several more times with trying to work the trigger in between. Finally got the hammer to fall and the trigger to reset. Cylinder stop also seemed to function normally at this time. By the time I gave up on it, it functioned single action as normal. Trying to work it double action began as ever 10th or so pull of the trigger would spin the cylinder, but not move the hammer more than just the smallest amount. Took it back to the gun store and now it functions double action if you let the trigger fly forward, but if you ease it back to the "home" position, the next pull will just spin the cylinder and not engage the hammer. I left the gun with him to be sent back to S&W. While the gun as it stood was in much better shape than after its initial lock up, I do not believe I should have to release the trigger any certain way to make an over $800 revolver function as designed. My concern is that a gunsmith at S&W will pull the trigger a few times, see that it works (in his eyes) as intended, and ship it back with no issue found. It is also a concern to me that once i get it back, it will lock up again when I try to fire it double action. If they don't fix anything on it, what problem areas should I focus on? I am mechanically inclined, but I do not have experience with the disassembly of a revolver at all. All i want is what I thought was a super nice .44 to function as it should.
