This over-the-counter CO₂ replica of the GLOCK 19 is compact and handy, with the unmistakable look of the original pistol and plenty of power. In spite of its relatively small length of 186 mm, it fires 4.5-mm steel BBs (.177) with a muzzle energy of up to 3 joules and weighs a hefty 717 g. This faithful replica comes with a metal slide and a real trigger blade safety.
