What is the Glock 17's locking system?

• A. Rising barrel
• B. Glock 17 type of feed
• C. Blocks trigger
• D. Firing pin safety

Answer: (A)

The Glock 17 uses a short-recoil, tilting-barrel locking system. After firing, the slide and barrel move rearward together for a short distance while the barrel remains locked to the slide. A locking block then allows the barrel to tilt (rise slightly) relative to the slide, unlocking from the slide so the slide can continue rearward to eject and cycle. This motion—where the barrel changes angle as it unlocks—is why the description “rising barrel” fits best. Other options describe features unrelated to locking the barrel: one refers to how cartridges are fed from the magazine, another to a trigger-block mechanism, and while Glock does have a firing pin safety, that safety is separate from the locking system.
