Yep. The Firepower Pack for ME2 was the same price and only had three weapons.

But there's bound to be additional weapon DLC packs. We don't have the Striker AR, the Kishock Harpoon Gun, and the three Earth pack weapons in single-player yet (although those may be added in future mission packs like the Raider and Argus are being bundled with Leviathan).
