Things I liked: I bought this for dry fire training. It has a great weight and feel to it.
Things I would have changed: Durability of internal parts. Safety could be tighter. Accuracy could use some work. Sights could be better. Shipping to Canada was insane and cost 70% of the gun's price. Chews through CO2 pretty quickly. I got about 4, 10 shot mags from one cartridge.
What others should know: Double action broke after a week. Gun fires in single action so it still functions. Sometimes magazines don't seat all the way and require a firm slap to seat. If you plan to training with CO2 it's quite good but if you're only dry firing it's only okay for the price. Be prepared to buy A LOT of CO2.
