I have a HK P2000 and my mags have factory mags w/ finger ext. and are made of plastic. I went to a range and a DHS CBP Officer was shooting his duty HK P2000 next to me and his gun had same factory mags but his base plates were made of rubber not plastic. He said that when you drop your mags on the ground the plastic plates have been known to crack so CBP asked HK to have base pads made of rubber. Does anyone have a source for these HK rubber base plates. I also understand HK makes flat base plates to make the gun more concealable. Anybody have on-line sources?? thanks.
