The Airsoft Fairy talks about and tests this upgraded Tokyo Marui Glock 18C Gas Blowback Pistol and it looks like something you would love to use as a primary in CQB games... "This video is showing the testing of the re-enforced slide and rear sight of Tokyo Marui Glock 18c airsoft pistol and how it performs."
The Airsoft Fairy considers the KJ Works Non-Blowaback Pistol to be the most powerful airsoft pistol he has fired. Based on the Ruger design, this usually has an initial muzzle velocity of 300fps and comes with a 16-round magazine.
