(NOT NECESSARY TO READ...SKIP TO SECTION BELOW) First, before you guys all yell at me for not using the search function, I used Google, and I used the Airsoft Society search function to search for "cold weather", because "kwa ns2" is "too short". Lol, what a fail. So, I am still searching for a gas blowback pistol to use. I live in Colorado, so it has to be good in cold weather, which means it needs to be CO2, or... I have heard that the KWA NS2 gas system works good in cold weather. I've heard that it's better and worse than CO2 for cold weather. I don't know what to believe about these mixed reviews though, so I'm asking you guys. How many shots can a KWA NS2 pistol pull off in 50 degree or lower temperatures? By the way, I'm mainly looking at the KWA M93R II or USP Tactical.
