In case anyone is interested, I found a nice magazine extension from hkparts.net. It gives you a place to put your pinkie and adds two extra rounds to the magazine. I havent shot the gun with this extension on, but will later on this week. Here is the link: http://www.hkparts.net/shop/pc/viewPrd.asp?idproduct=17972&idcategory=0 . I will try to post a pic or two.
