Things I liked: Excellent trigger, both single and double-action. Actually, better than the "real" gun. Quite accurate for a CO2 pistol. I'm able to consistently hit tin cans at 20 yards shooting off-hand. Very well built, weighted like the real gun. About 80 shots per CO2 cartridge, 50 of which have plenty of power.
Things I would have changed: Paint the front sight a "glowing color" one can see in bright sunlight. Otherwise, this gun is about perfect.
What others should know: Very high quality pistol, just like the real thing. Rear sight is easily adjustable with the allen wrench provided. Looks and feels like the real thing. Possibly, the best Walther copy available. They did everything right--even for southpaws.
