The grey Gen4 frame distinguishes this G20 from standard models. Glock produced the color exclusively for Lipsey's, resulting in a limited-number release prized by enthusiasts.
Chambered in 10mm Auto, the G20 delivers high muzzle energy while maintaining controllability through Glock's dual recoil spring assembly, introduced with the Gen4 series to reduce felt recoil and extend service life.
The pistol retains Glock’s proven striker-fired action with a 5.5-lb connector, offering a consistent trigger pull from first to last round. A reversible, enlarged magazine release supports rapid, ambidextrous operation.
A nitrided matte-black slide rides on integral polymer rails and hosts fixed polymer sights—a white-dot front and white-outline rear—providing a clear sight picture in varied lighting.
The modular backstrap set allows shooters to tailor grip circumference, while the full-size frame houses 15-round magazines, marking the highest factory capacity available for a 10mm handgun at the time of release.
