Not your standard golden AK or Dragunov. These were on display at IDEAS Pakistan 2008 by POF (Pakistan Ordnance Factories, the Pakistan stated owned arms and ammunition manufacturer).

The submachine guns are POF’s SMG-PK (Licensed built H&K MP5K). The Rifle is a G3A3.
I am not sure about the pistol or shotguns. The pistol could be a stainless/plated framed version of the POF PLK-30 7.62×25mm pistol.
ATI have announced the GSG5-PK pistol.
The new GSG-5PK pistol is a .22 Long Rifle HV Caliber with a barrel length of 4.52″, total length of 15.275″ and a total height of 10″. It weighs in at a dainty 5.2 lbs. It has an alloy frame construction and features a magazine safety and click-adjustable target sight. At a MSRP of $549.95, the GSG-5PK pistol is the perfect partner to the original GSG-5 rifle model.
It is basically a GSG5-P (pistol) with a shortened barrel and MP5K style handguard. Some photos (click to expand):


Hat Tip: SayUncle
Murdoc @ GunPundit found a photo of 3rd Infantry Division troops examining a pile of H&K MP5K briefcase guns presumably in Iraq.

I have always thought this type of gun would appeal to tin pot dictators like Saddam. Why not just conceal the MP5K under a coat and then have the advantage of sights, trigger control, quick magazine change etc.

Federal agents said Monday that these guns were found in T.I.’s home. The rapper, whose real name is Clifford Harris Jr.. was arrested over the weekend on federal weapons charges. He was ordered to remain in custody at least until Friday.
The machine guns: two mac-10’s and one MP5K, with suppressors:

High cap magazines seem to be in fashion

The firearm in the middle of the above photo appears to be a Calico 9mm LIBERTY III pistol with the distinctive 50 (or 100) round magazine that sits on top.
