Fox Airsoft give their take on the CZ ACCU Shadow CO2 from Action Sport Games (ASG)... "The ACCU Shadow is part of the CZ Shadow 2 family and is an enhanced competition version of the popular CZ-75 style pistol. All Shadows have a metal slide and frame but the ACCU Shadow features a recontoured frame, exclusive grips, and most of all a single-action only trigger with a barrel bushing. The sights are enhanced with a front fiber optic. This is a CO2 powered gas blowback pistol brought to us by Action Sport Games."
