Stuff like this is why you have more guns than you can remember and have totally forgotten where many of them were put for "safekeeping".
As you get older it seems you don't really need any help to "forget" how many you might have or where they might be.
They are unlikely to really do a good search, most likely trying to bully you into handing them over, or grab what they can in a smash and grab like your average burglar would, anything they can see, possibly try to get you to open a safe or rip the keys off you if it's keyed.
But it would help to have some in safe keeping off site or where you can get to them later in case they decide to do a full detailed search.
However it's all for show, as while a gun is useful, your local cornerstone gas station either with or without a visit to your local hardware store will get you way better equipped to be "a danger to others" than some guns if you are trying to actually harm people not expecting it.
What they really care about is you not being able to quickly defend yourself when they or their "allies" of Communists jump you by surprise while you are trying to enjoy a nice evening or peaceful night's sleep.
However even then, if you just go middle ages on them and do some planning with "fortifications".... oh the fun that can be had...
