I finally got the opportunity to shoot the ASG CZ P-09 Duty CO2 Blowback Pellet/BB Pistol that I saw back in January of this Year while I was attending the SHOT Show in Vegas. Essentially the ASG CZ P-09 Duty is built similarly to the Umarex PX4 Storm and Gamo Blowback Pellet Pistols. They all use double sided stick based rotary magazines that hold 8 rounds in each end. They also all shoot with a single action hammer (set to the cocked position by the blowback action) while the first stage of the trigger rotates the rotary magazine and indexes a round. So I would consider them to be single/double action hybrids.
Anyways, on with this field test shooting review... As per my normal field test shooting reviews, I shoot some rounds through my Chronograph to get an average fps rating and I also step back 30 feet from a paper target and use a semi rested position to place a series of rounds downrange. I decided to allocate 8 rounds for each test station since the magazine holds 8 rounds on each end.
