Why might the Glock platform be described as "one and one-half action"?

• A. The Glock platform lacks a sear mechanism.
• B. The Glock platform operates solely in double-action mode.
• C. As the slide moves forward, the sear engages the striker and draws it partially rearward.
• D. The Glock uses a hammer to strike them.

Answer: (C)

The Glock platform is striker-fired, so firing involves two steps: the slide’s movement pre-cocks the striker, and the trigger releases it. As the slide moves forward, the sear engages the striker and draws it partially rearward, placing it in a pre-cocked state. When you press the trigger, the sear releases the striker, allowing it to move forward and fire. This combination—slide-assisted partial cocking plus trigger release—feels like “one and a half” actions, unlike a hammer-fired pistol (which uses a hammer) or a pure double-action system.
