About a month ago, I purchased a S&W 637-2 Airweight from a private party. The gun was brand new in the box unfired. Along with it, I got an HKS speedloader and a Hogue Bantam grip along with 100 rounds of .38 hollow point ammo. The whole package was quite a deal.
Last week, I took the gun out to the range and fired it for the first time. I put the 100 rounds of ammo thru it. During that time, I noticed the barrel and front sight was not centered to the frame in a way that the sight is not centered to the sight groove on top of the frame and the ejector is not centered to the locking bolt and spring.
Today I decided to clean the gun. While cleaning, I found that the part of the frame underneath where the barrel is inserted to the frame has a large crack in it. There also seems to be a little bit of excess solder there as well.
So what I'm trying to find out is if its common occurance on S&W small J frame revolvers for the barrel and front sight to be installed off center from the frame? Also, is the crack in the frame under where the barrel inserts into the frame normal? If both of these are not normal, will S&W fix them under warranty?
Any comments and/or feedback on the above issues would be greatly appreciated.
