Looking for a M&P C.O.R.E. grip/palmswell. Can't get these through my normal channels - hoping someone with a new gun wouldn't mind selling/giving me one. Has anyone shot with one of these - any noticeable difference between the old grip and the new grip?? Send me an IM and let me know what you got - no worries about size, just need a grip. Will pay for item plus shipping!! Than you in advance!
