In the XD-M, what happens internally when the operator places their hand on the grip and deactivates the grip safety?

• A. The grip safety rotates around its pin, clearing the sear's path.
• B. The sear resets and the trigger is blocked.
• C. The extractor arrests the case.
• D. The hammer drops immediately.

Answer: (A)

The main idea is that the grip safety must be depressed by a proper grip to let the trigger do its job. In the XD-M, when your hand wraps around the grip, the grip safety rotates around its pin, moving out of the way and clearing the sear’s path. That clearance lets the trigger move the sear and release the striker, allowing a shot to fire. If the grip safety isn’t engaged, the sear remains blocked and the firearm won’t discharge. The other options don’t fit because they involve actions that aren’t how this grip safety operates: there’s no hammer in a striker-fired XD-M to drop, the extractor isn’t engaged by the grip safety, and the sear doesn’t reset while the trigger is blocked due to grip safety behavior.
