DEFTAC Weapons and Firearm Practice Exam

The idea being tested is how Glock defines its major assemblies. In Glock training, the five major assemblies are the frame, slide, barrel, magazine, and the recoil spring assembly. The trigger sits inside the frame as part of the trigger mechanism, but it isn’t counted as one of those five major assemblies. That’s why the trigger is the correct choice for something not listed among the five major parts. The magazine, barrel, and slide are clearly major assemblies, matching the standard breakdown.
