J Man 3,
I checked out the 945. I encountered the same slide problem as Shifty. I pulled the slide back and released it. The slide moved forward, then slowed to a stop much too soon, leaving the chamber still open and exposed. This may just be a lack of lubrication or a lack of final machining. Either way, it's not my responsibility to explain or defend a multi-million dollar company's quality control. Hopefully, the final production models will work smoothly. Knowing KWA, they will be just final.
The 945 is a compact pistol, comparable in size to the Baby Hi-Capa. It was far too small for my hand. J Man 3, our hands are about the same size, IIRC. I don't know how it will feel to you. I don't have any emotional investment in the issue, I'm just sharing my thoughts.
I asked about release date and cost. Both are TBA.
