The G34 Gen 3 is Glock's long-slide 9mm built for extended sight radius and controllable performance, with a factory 5.31 in barrel and polymer frame. This example retains the standard striker-fired action and trigger safety system, along with a Glock accessory rail featuring a single cross-slot.
It is a U.S.-made pistol with the slide marked "GLOCK 34 USA 9x19" and the frame molded "MADE IN USA - GLOCK, INC., SMYRNA, GA." Additional markings include a P in pentagon inspection mark and a US mark on the barrel underside. The slide, barrel, and frame carry matching serial numbers.
The long-slide configuration includes the factory top lightening window. Sights are the original polymer notch-and-post set, with a white-dot front and white-outline rear. The magazine release is the standard left-side design.

Custom work includes full-coverage grip stippling on the sides, front strap, and backstrap, providing a distinctive texture. An aftermarket engraved slide cover plate is installed, adding a decorative touch to the rear of the slide.
