Things I liked:Very realistic, good weight, balance, feels solid & well built. Grip is the only thing that is a cheap feeling. It does it job and conceals the CO2 cartridge but somewhat compromises the overall realism of the piece. Gun needed to be lubed with silicone to function properly, cylinder was a little sticky out of the box. Very nice gun overall! 100-120 shots per 12gm CO2. Excellent groupings, 1-2" @ 15 ft or so. Loading, firing is VERY realistic. Would be good for firearms training. A whole lot less expensive to shoot than the real firearm and you can shoot this one in your basement! Have owned this gun for a month, put 1000 plus rounds through it and no problems. Very pleased with this purchase. Things I would have changed:Would look into redesigning grip and having more authentic feeling grip. What others should know:Lube gun with silicone before using. Lube CO2 cartridge each time you change one to keep O-rings lubed.
