The Gen3 G34 pairs a 5.31 inch barrel with a long, competition-length slide that includes a top lightening window, plus chamfering at the muzzle and along the slide top. The slide has rear serrations only and a black finish.
The barrel is steel with a nitrocarburized treatment and polygonal rifling. The pistol uses Glock's short-recoil, tilting-barrel lockup and is striker-fired.
Sights are factory-installed: an adjustable polymer rear with a white-outlined notch and a fixed white-dot front, offering a clear, straightforward sight picture.
The black polymer frame includes an integrated accessory rail and a standard, right-side-only magazine release. Safety is handled by Glock's Safe Action system with three passive safeties.
