Sadly, this issue keeps popping up regardless of model number. I have a thread on here from last year, a brand new 629 was shooting a foot to the left even with the rear site cranked all the way to the right. It ate up my whole summer, but after sending it back twice it's perfect now. It shoots so nicely, and I went through so much trouble getting it to this point that I'll never sell it. It does make you think twice about wanting to buy a brand new S&W again however. Nice guns for sure, but what a hassle it can be if you get one that shouldn't have left their factory. They will eventually fix it...I had to get very demanding upon the 2nd return and I doubt it would have been fixed had I not been. Mine clearly got extra attention that second time in. There are also some excellent smiths across out country that specialize fixing S&W revolvers with canted, crooked barrels, out of spec frames, cones, poor triggers, misaligned sites, etc. So for me, it worked out but that was a lot of effort, phone calls, wasted ammo, shipping, driving to the package place to sign for the gun, etc. I would gladly pay a little extra to just buy a new S&W take it home, and start enjoying it.
