Things I liked:The weight, the features and feel. The drop out CO2 mag, single and double action. Trigger pull. Things I would have changed:The way the magazine is secured. The pellet mag falls out very easily once you open the slide. I have dropped the magazines on the ground many times forgetting to cup my hand around the opening as I open it. What others should know:This was my very first airgun purchase/experience. I am quite pleased with it. I bought the laser sight for it and it's very accurate. Being new to airguns, I did not know what to expect for power for a gun like this. I'm somewhat disappointed by the amount of power it has. Maybe my expectations were too high, but I was surprised to find out that I can not even penetrate a simple plastic spring water bottle with this. Otherwise I love it. I get about 90 shots per co2 cartridge.
