Take a look at the entries again. One bullet point in both the Mil.Temp. Command Squad and the Mil.Temp. Scions reads, "A Tempestus Scion with a vox-caster may replace his hot-shot lasgun with a hot-shot laspistol." Thus, the hot-shot lasgun is not replaced by the vox caster. The model has both standard, but can replace the lasgun with the pistol if you are all about the WYSIWYG and don't want to do conversion work.
