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

• A. Because it uses a traditional double-action mechanism only.
• B. Because the trigger connects to the hammer only at one point.
• C. Because the slide movement interacts with the striker to partially cock it.
• D. As the slide moves forward, the sear engages the striker and draws it partially rearward.

Answer: (D)

One-and-a-half action describes a mechanism where part of the cocking happens during the slide cycle, and part happens when you pull the trigger. In a Glock, the slide’s movement into battery interacts with the striker through the sear to cock the striker partially. As the slide moves forward, the sear engages the striker and draws it partially rearward, storing some energy. Then you pull the trigger, which completes the cocking and releases the striker to fire. This combination—slide-driven partial cocking plus trigger-driven release—is why the action is described as one and a half. The best description of this process is that, as the slide moves forward, the sear engages the striker and draws it partially rearward.
