Here’s an inside look at the Glock 18C which was designed for the Austrian Counter-Terrorist Unit (EAO Cobra). This 18C series means its compensated with features like this: -Keystone cut at the top of slide near the front with 4 slots angle towards the barrel. -a pocket back at the top near the rear of the slide to make this gun run fast.
With a cyclic rate of fire that runs as fast as 1,200 rounds-per-minute, the slide of the G18C can sometimes jog so fast that it can outrun the magazine.
Larry Vickers from Vickers Tactical in the above gives a short overview of the compensated Model 18 Glock select-fire 9mm handgun before sending brass downrange in beautiful HD and Slo-mo. A true machine pistol and not a conversion with a fun switch modification on a more commonly encountered Glock, the 18 features a slide-mounted selector switch and is pretty rarely encountered due to the Hughes Amendment, which tragically relegates it to only LE and military.
