Τhis BB air pistol is styled after a real well known blowback pistol. This means it functions very similarly to the real steel. It is a very hefty gun made almost entirely from metal and has a very snappy blowback action which adds to its shooting realism. Even the magazine looks and feels like a real 9mm magazine with similar weight and dimensions. The KMB-77AHN of KWC shoots very accurately for a BB airgun and has fairly decent power considering its blowback function, though this does result in heavy usage of CO2.
The only problem with the classic weapon is that it is missing a few of todays more modern features and that's what is so nice about the new KMB-77AHN of KWC BB Pistol, it takes an all ready great design and makes it even better by adding the Tactical style trigger and hammer, textured grips, ambidextrous safety, adjustable white dot sights and rail for add on accessories.

Trigger Pull: The trigger pull on the KMB-77AHN of KWC Blowback BB Pistol is exactly what you would expect from a true Single Action styled Pistol. It has a short take up and then a nice and light crisp pull to it. Because of the similar mechanics not only to the trigger but other aspects of this gun, it would make an awesome low cost trainer to be used when your real weapon cannot be.
Accuracy: During shooting tests the KMB-77AHN shot at a target from 20 feet away in a semi rested position, and it performed well getting a 2 inch grouping just a bit off center of the target. The sights are adjustable for windage so zeroing the KMB-77AHN of KWC would not be much of a problem! An initial Chrony testing puts this gun right in the 300-320 fps range which is just fine for this style of heavy full realistic blowback action BB shooter. It was also managed to get three very good magazine worth of shots with some extra CO2 left for a potential 4th magazine. If you slow your shooting down and let the gun and CO2 warm up between magazines you can get 4 magazines with this gun for sure.
Build Quality: KWC did a great job with the KMB-77AHN. The quality and build characteristics may even be just a bit better than my other blowback air pistols. Everything that should be metal is the same on this as the original, the slide and barrel wiggle are minimal and the finish seems to be wearing fairly well on this KWC airgun. I do expect over time fore some of the finish to wear off on the high points but this can also give the gun some character.
Realism: The KMB-77AHN of KWC airgun is as close as you can get to the real steel but with an obvious more modern Tactical look to it.
