Yesterday, I bought 2 new magazines at a LGS, a LC9 9-shot, and a LCP 7-shot. I cannot get the LCP extended mag. to engage and lock in to the frame, so I called Ruger CS. I spoke with a CS rep., who was very cordial and she promised to ship out a new extended LCP mag. come Monday, along with a postage paid return envelope for the defective mag. I'll keep you posted. BTW if you own a LC9 or and LCP, I recommend these extended mags., they really give my hand a better purchase on the pistol.
