The Glock 45 Gen6 9mm Luger pistol (brand part no. U64550203H2) is built on Glock’s sixth-generation platform, a redesign shaped around real-world hand measurements rather than a simple update to the Gen5. Glock built the Gen6’s grip around a new RTF6 texture that extends coverage into areas like the thumb rest for a more confident hold, paired with a flat-faced trigger for a more consistent press. The slide integrates Glock’s Gen6 optic-ready system directly, letting shooters mount a red dot without a separate adapter plate. With a 4.02-inch barrel, fixed sights, and 17+1 capacity, the G45 Gen6 pairs a compact-length slide with a full-size frame for a genuine duty-or-carry crossover pistol.
