If you are using the frag grenades from hl2 they use collision groups to specifically disable collisions between their physics objects and other objects (NPCs for example). Then they trace rays to fake it in their VPhysicsUpdate() function. That allows them to bounce off of the NPCs' hitboxes without those hitboxes actually being in the physics simulation.
It's possible that the reason they aren't colliding is this collision rule behavior. Try changing the collision group of the grenade or the other entity to COLLISION_GROUP_NONE and see if that fixes the problem.
