They have been on and off the list a few times. Finally they decided the cocker is the "double action" part of the gun and put it back on the production list.
As a side note, P7M13 Longslide sport pistols used to rule IPSC in the 80's in Europe and did very well in USA in the hands of grand master Bruce Grey (Grey Guns) shooting 9mm Major for team HK USA. He had over 200,000 rounds of 175 PF ammo through his P7 with no major breakages, a testament to the teutonic all forged steel design of the pistol.
