Has anyone figured out what, if anything, triggers the glitch in which companions do not get their weapons back upon exiting a casino? Anything that has been known to raise the odds of it happening, even, are helpful. I don't like them having infinite ammo. That and the invisible walls are really the only problems I'm having with the game at all.

If you don't want them to have infinite ammo just give them another gun.
About the glitch, when I shot up Tops (not for a quest) Boone came out without his gun, not sure if that was luck or not.

Giving them another gun doesn't really help, as soon as they run out of ammo on it they revert back to the infinite ammo unbreakable magic gun, hahah.

No it's a glitch, when you leave the casino sometimes your companions main gun is in your inventory. I know with Boone you can't give him his weapon back, the rest I'm not to sure about since it's only ever happened once with Raul.

Give them alot of ammo, Boone uses the Sniper Rifle and I just give him more ammo whenever I barter.


I know it's a glitch I just didn't know if shooting at Tops helped start the glitch, that was the only time it did that to me in 200 hours.

(SPOILER )Not just casinos I had the glitch hit me SPOILER at cesars camp . when I got off the boat they took my weapons and when I left they kept my companions weapons I know this cause if you go back and pickpocket the key off the main gate guard you can open the create and see them but if you take them back they attack you . Also when seeing Cesar the door guard won't let you in and says your companions have to with outside Even if you fire your companions and wait three days before going to cesars camp they still won't let you in . I seek c4 on the door guard and walk around the corner and boom I got in without being listed as hostile . Also I noticed my remote detonators kept getting taken every time I checked my guns so Now I don't leave my guns at any door I load them in box or can outside before I go in or to a place and leave a companion to guard the box .

Veronica never got her weapons back when I entered / left the Gomorrah.
Even if I left her outside they would disappear !
Now I keep her weapons in my inventory when I go into any casino.
