Well, also just looking at the first page, while I think there are analogous circumstances where this would've been infuriating (e.g., the government executes an unrelated search warrant, discovers both marijuana and the gun and charges him with it), in this case, it seems as though he both surrendered the gun to them and freely admitted to using marijuana which he also directed them to. That said, the search warrant was related to terrorism and it's very likely it would've authorized the agents to search for any drugs and firearms or other weapons.
