This HK45 CO2 BB air pistol shoots BBs at 400 FPS and includes a 20 round magazine for semi-auto operation. This is the authentic licensed replica of the popular HK45 firearm. Licensed Trademark of Heckler & Koch GmbH
Trigger Pull: Trigger pull on the Umarex HK 45 Metal Slide CO2 BB Pistol is double action only but doesn't feel too bad, it has the traditional longer double action pull but I did not find it to be too heavy and the release point was fairly predictable for me allowing for some good overall accuracy.
Accuracy: I got a bit higher FPS then claimed at 420 FPS with a 5 shot string using a brand new CO2 with RWS 5.1 grain zinc coated steel BBs. From 30 feet away shooting on a paper target using a semi rested posting I was able to place 10 BBs within 1.5 inches, almost close to a 1 inch grouping. The shot placement for me was just a tad to the left and a bit down but several shots hit the bulls eye so out of the box accuracy was really good on this low cost BB pistol.
Build Quality: The Umarex HK 45 Metal Slide CO2 BB Pistol is built fairly basic with few moving parts so there is not much to go wrong, the fit and finish is good and there is metal where it needs to be internally and also the trigger, magazine and slide.
Realism: The Umarex HK 45 Metal Slide CO2 BB Pistol is a very good overall HK 45 replica in terms of size and looks, it has full HK licensing and even has a metal slide and polymer frame like the original real steel HK 45. It is a bit lighter bit not by too much. There is no working slide and the slide catch/release and hammer are molded into the gun. The only working parts would be the safety, magazine release and trigger.
Inexpensive overall decent BB gun

Metal where it matters, slide, magazine, trigger, internals
