Here's Tim of Airsoft GI putting this big pistol from KWA through the paces... "The HK45 is the latest hand gun to come from KWA and it is sure to impress. The HK 45 is based upon the real steel gun of the same name from Heckler And Koch. The real steel version of this gun is chambered in the .45 ACP caliber and was designed to meet requirements set by the U.S. Military Joint Combat Pistol program to replace the 9mm M9. After the program was terminated in 2006, HK decided to continue production and offer it to law enforcement and military groups.

KWA pulled out all the stops with the HK 45 and spared to expense to ensure that it lives up to its real steel counter part. This gun features a railed lower receiver made from high strength polymer and features a textured grip to ensure that the user maintains a sturdy hold onto the gun. The lower receiver also features an adjustable back strap which allows the user to either install the slim line or swelled strap to contour perfectly to their hand. The lower frame also houses the ambidextrous slide lock, magazine release and the fire control that also functions as a de-cocker. The slide of the HK 45 is made of an aluminum alloy which is both durable, yet lightweight to allow for a very crisp recoil. 3-dot style combat sights allow the user to quickly and easily acquire targets with the HK 45 even under low light or high intensity conditions. Finishing off the slide are beautifully engraved HK trade marks that really take this gun to the next level. Whether you are looking for a perfect replica of the real steel HK 45 or you are simply looking for a top notch hand gun with ambidextrous features, the HK 45 from KWA is a must have!"
