Just finished populating a stripped frame today, the second M&P pistol I own, not bad easy straight forward no issues. Its an M&P 9c M2.0 FDE frame and a 4.25" Black slide. Eventually it will have a C.O.R.E slide with a threaded barrel just because options. Can't wait to bring it to the range. I would do this again but I have learned that the compact magazine is I have purchased does not fit, kinda small. I now learned that the magazine i have is probably a 1.0 compact which is not compatible to 2.0 compact or miss packaged has a compact but had a sub compact magazine inside. Is there any other quirks to the M&P family? Will an m&p compact 1.0 magazine function in a 2.0 sub compact? Other than that I can't wait to get it out to the range and compare it against other compact pistols. Thank yous.
