This G34 Gen 3 is built around a long slide and 5.31 in barrel, delivering a generous 7.56 in sight radius. The top lightening window reduces slide mass, and rear-only slide serrations provide a familiar Gen 3 profile.
The Gen 3 frame includes finger grooves and a non-interchangeable backstrap for a consistent grip. A Glock single-slot accessory rail supports compatible lights. Controls include a standard left-side magazine release.
Sights are a polymer white-dot front paired with a Glock polymer adjustable rear, allowing precise elevation and windage settings. The Tenifer (ferritic nitrocarburizing) finish enhances surface hardness and corrosion resistance.
Chambered in 9mm Luger with a standard 17+1 capacity, this pistol has an overall length of 8.82 in and weighs 23.10 oz without a magazine. It uses Glock's Safe Action striker-fired system for consistent operation.
Made in Austria, this example shows an AT stamp on the barrel hood and "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." on the frame, aligning with typical factory markings for this model and era.
