JCP meaning in Governmental ?

The Joint Combat Pistol was the name for a former US program for a new military sidearm to replace the M9 Pistol, extant from late 2005 to early 2006. The program was started in 2005 and run by USSOCOM. It is the result of a merger of two earlier programs, the army's Future Handgun System (FHS) and the Special Operations Forces Combat Pistol. Current requirements for the JCP include being chambered for caliber .45 ACP, having an integrated Picatinny rail, including day/night sights, and being capable of accepting a suppressor.

On March 10, 2006 a modification to the earlier request was made, changing the name from Joint Combat Pistol to Combat Pistol. The number of pistols sought was reduced from 645,000 handguns to 50,000. This effectively reverted to the SOF Combat Pistol program in terms of its scale, as the army dropped its participation. In the autumn of 2006, the Combat Pistol (CP) program was suspended indefinitely.

In a 2007 supplemental session, the congressional defense sub-committee appropriated $5 million to a Joint Combat Pistol study.
