spear, lance, javelin
槍 centers on a long, pointed weapon used for thrusting or throwing: a spear, lance, or javelin.
槍 combines 木 (wood) with 倉, which likely contributes the sound and may relate to a storehouse or container, suggesting a wooden shafted weapon. The exact historical development is uncertain.
A wooden (木) shaft with a sharp head stored in a warehouse (倉) ready for battle: that's a spear.
For ソウ, imagine a soldier (ソウ) thrusting a spear into a warehouse door: soldier -> ソウ, and the spear is the weapon he uses.
