The popular H&K KWA pistol is now updated with the KWA NS2 gas system. The new gas system increases the performance and improves the overall reliability of the gun.

The NS2 internal gas delivery system is a KWA patented design that utilizes an advanced lightweight composite gas piston with a two-stage internal expansion chamber that delivers the gas more efficiently than that of its predecessors. The NS2 design also increases the weapon cycle rate and provides for a crisp, realistic blow back action.

Other parts of the pistol like the recoil springs, recoil springs guide assembly, hop-up chamber, magazine followers, has also been improved along with a new magazine that is milled from a solid steel billet. This new construction strengthens the magazines structural integrity and increases pressure carrying capacity. The magazine feed-lip has also been reinforced.

Things I liked: I have been looking for a good gas blowback pistol and this gun was the right choice. It is sturdy and reliable. The blowback action is positive. It is accurate enough to shoot the wasps that pester me in my back yard. Out of all the airguns in my collection, this is one of the most popular with my sons. Lots of fun !

Things I would have changed: Nothing

Things I liked: KWA H&K USP 45 is best pistol on the market. Truly engineered to outperform. Pistol is constructed with an aluminum slide with 3 dot sights and a polymer checkered lower frame. Grip is deeply checkered which gives you a very solid hold. Trigger is light and crisp in both single and double action. The USP is extremely accurate out to 100' especially with a heavier 25g bb. It's fantastic on gas consumption with the NS2 system, even in the cold winters of western new york. The USP can be carried cocked and locked for rapid deployment. It has a safety and decocker for added safety. Magazine is full metal and holds 25 bb's. This is now my third KWA pistol, the other 2 being the usp compact and the usp compact tactical, all of which perform superbly. You will never go wrong or be disappointed buying a KWA H&K USP.

Things I would have changed: Absolutely nothing...KWA H&K USP's are built to last and outperform...10/10

What others should know: a slide adapter needs to be purchased to add a laser or otherwise very limited. Buy from because they have the speediest order processing...and very fast shipping as well.

Things I liked: All the levers on the gun works realistically. The weight of the gun is a little heavier than what I remember the real gun felt like but I rather it feel heavier than lighter. The new NS2 gas system is amazingly proficient, the gas does not leak so I can keep the gas in the magazine for days and still have the same charge the next time I use it. Plus this gun shoots a lot harder than most guns using Green Gas. Gun is also very accurate. I've only shot at things up to 15 feet but the difference in speed and accuracy on this gun compared to my old WE 1911 is astounding.

Things I would have changed: I wished the grips were customizable. The grip on this gun is made out of ABS Plastic and although does the job well, it feels uncomfortable.
