The original version of the famed Glock 17 holds an important place in many weapons collections. For those who want to share the excitement of owning a Glock, the over-the-counter CO2 version is the perfect solution. This replica is fully faithful to the original, with all of its markings. But it was not made to be kept in a display case. With its heavy metal slide, powerful blowback and all-in-one magazine the Glock 17 promises hours of fun shooting 4.5 mm steel BBs.
