I just purchased a 2.0 CORE 5 inch from Palmetto. I picked up at dealer this afternoon and found some weird things on it. The Gold marking (Pro Series) was place over the M&P cuts in the frame also it has some weird front slide serrations that I have not been able to find online anyplace. If you can tell me or send me a link to what gun came with these serrations I would really love that. I’m going to attemp to upload the pics. Thanks for any help in advance.
