I had always been curious about the guns that I had seen in toy and hobby shops around Japan. They looked incredibly detailed, but I never imagined they were BB guns. I had always figured they were models or kits to be built by the same guys that bought the model cars, airplanes, and military vehicles.
Then, about 18 months ago, a guy I work with suggested we make a bad movie about cops, gangsters, or zombies…didn’t matter, as whatever the plot, we would need prop guns. It was time to go shopping! I bought the Maruzen Walther P99 while my buddies picked up handguns from KSC. It had begun.
The P99 felt great in my hand, with a balanced weight distribution and a solid feel. As this was my first gun, I bought used. This was a mistake. Seems the Maruzen mags suffer from quality issues, and the mag release can become worn which doesn’t allow the mag to sit high enough in the mag well. I bought the P99 in June and played with it extensively for a few months. I would usually get a single mag between gas refills. Once it got cold out the gun became useless. By October the gun would hardly get five or six shots off before the gas would psssst out off the mag. I posted some YouTube vidoes asking for help and it looked like the mags were causing the issues. I decided to sell the P99 and it sold almost immediately for just under what I paid for it. They buyer wrote that it worked great and that he was pleased with gun 
I had yet to get into airsoft gaming so I had no knowledge or interest in power, accuracy beyond five to six meters, or any of the other details that would be so obvoisly important to a review.
The P99, while unreliable, was fun to shoot, and was the catalyst that got me into airsoft.
