So I've been shooting one of these lately and after 200 rounds the takedown allen screw wants to back out. After snugging it up it goes 100 rounds and loosens up again. So, on goes the blue loctite..problem solved, even though it shouldn't loosen up. I would think fine threads would have been a good idea. Fast forward to today and about 600 rounds since the gun was new, the ejector is MIA ! I have no idea where it is or why its gone. Seems like I'm not the only one though, I found a thread on the S&W forum where it happened to someone else as well. Even though the gun feels good, shoots nice ( when its not falling apart) and is accurate, I'm afraid it might be a pos..what the hell is going on with S&W ?? I guess I'll have to contact S&W and ship it off. In all my years of shooting and gun ownership I have never had to deal with a brand new gun falling apart.
