So I'm not sure when exactly this happened. I think it was when I was visiting the Gomorrah on behalf of Mr. House and finished his task. Some time later when I entered into a combat I noticed that Arcade was just kinda ducking down and cowering instead of shooting his plasma pistol. After the fight, I checked his inventory and all the weapons I gave him to carry were gone. I guess he didn't get them back when we left the casino. Is there a safe that these weapons get put in when they are taken from you?

Strange they should always have their default weapons on them, i have had instances where i gave out weapons and they have been shot at and have broken causing the compainion to drop them, but to not have their default is new to me if thats what you meant.

I dont believe they are stored in any physical safe though.

I gave Boone the special guass rifle. While we were sniping some Legions he said it was a piece of junk and pulled out his sniper rifle. No clue where the gun went, but we were hidden and not being fired on yet so I dont think it was shot out of his hand. It was gone from his inventory and not lying on the ground. Odd.
