This may be a silly question, but here it is anyway. I just picked up a new 642, and overall the fit and finish is nice. I did notice one thing though, that caught my attention. It's a little hard to describe, but where the ejecter rod screws into the yoke (crane?, I’m not sure what the part is called, but it is the piece of stainless that the ejector rod is screwed into), I noticed that there is a bit of a “lip” between the stainless and the aluminum frame. Looking at the gun in profile, the stainless yoke/ aluminum frame is completely flush with each other from the base of the yoke, up to the area where it angles and becomes flat (by the ejector rod). The stainless section where it curves up and around the ejector rod is not flush with the aluminum frame. Looking at it from the side, you can see a little aluminum “lip”. Is this just a cosmetic defect? Do any of you who own a 642 see this on your 642's? Maybe I'm being a little too finicky, but I couldn't help but to notice this. Would any of you be bothered by this? The gun functioned fine.
