I could not get a good in-focus picture of this, so I will describe it as best as I can. Gun Disassembled; looking at the frame top down; right hand side by the hammer; imagine where the clip would go inserted into handle; now look directly to the right; at that point, you should be looking at what should be a black piece of metal, but instead, there is a small peening where I see silver metal. It is about the size of the tip of a pen. It is a small spot. I have not fired this gun since my 200 round break in test period. I have racked the slide and chambered rounds/ejected rounds, several times to either get it ready for storage or CCW. I don't know that it would interfere with gun function, as it does not appear to, BUT . . .
