if they suspect they are related to a crime, they are going to keep them until they have reason to believe otherwise. If there is still an active investigation concerning this crime and you are still a "person of interest", you aren't going to get them back until you are cleared.
I haven't checked but the drugs in the same residence may allow them to confiscate the guns.
so, the first thing you do is go the the police agency the took them and ask them how to get your guns back. I don't know what you mean by they aren't giving you a straight answer. Maybe they are inferring you are still under investigation and aren't getting them back until they have cleared you or the case.
