To be honest when I got the KWC Airsoft BB shooting Makarov, I was not all that awe struck, the lack of a working slide, DOA trigger and screw holes in the slide put me off just a bit. This Airsoft pistol did warm up to me a lot once I shot it, I was surprised by the very high fps and how accurate it was for such a low cost Airsoft pistol. I can really see this gun being used as a backup or sidearm in an out doors style Airsoft game where you may need to shoot targets out at range where other lower powered pistols just would not be able to get out to. The Umarex Makarov has always had a place in my heart, it is just a really good little CO2 BB pistol for the price with mostly all metal parts, a working slide, single and double action trigger and very good overall performance. In my books you can not go wrong choosing either of these Makarov replicas so choose wisely!
