Things I liked:I also have the Baretta XX-TREME, and I perfer this gun. they are both very acurate, easy to load, and require little maintenance. But the Walther is much less heavy and easier to operate.
Things I liked:The 2 12gram CO2 cartridge make this last quite a long time compared to my Cybergun Mini UZI. The 6 round burst has an incredible "Clacking" sound, like a real gun! I gave this gun to my son when he graduated from his beginners pistol and he has no problem operating and loading this gun. An excelent choice! Things I would have changed:The only thing I would like to see is an adjustable rear sight.
