KWC G17 Custom features a stylish pistol frame that has been known for years before the introduction of the similar pistols that uses polymer body. The rather straight-shaped grip of the typical full-size KWC G17 is of a comfortable and ideal shape, at least for many shooters especially with the raised beaver tail. This is a well-built gas blowback pistol, which is mechanically and physically very solid. Hard-kicking blow back system with CO2 gas is an incredibly pleasant feeling. The trigger design means that accidental discharge is prevented unless you deliberately pull the trigger with your finger. One of major changes it features is a metal slide which allows a stronger recoil from every shot. The hop-up dial can be adjusted once you take apart the slide and turning the silver screw. Disassembly is exactly like the real thing. Pull down on the disassembly lever and move the slide forwards off the frame.
