The highlights are his silly trans flag pistol and the giant Ruger rifle that he named after a pair of anime tiddies. I'd hazard a guess the former is what he carries with him routinely, i.e. when he was allegedly packing while Kindness quit her nannying gig.
As far as the lockbox notion we really don't know much either way, but on pure irrational bias I'm going to say he probably takes a kinda laissez-faire approach to gun safety arrangements.
ETA few more details: a survey of twitter search indicates that yes, these are his two personal weapons (although the tranch collectively owns many more):
Ruger 57, he calls it "Dominique," the rails are painted in trans pride flag colors.

This is the cheap American version of the internet-famous FN Five-seveN meme gun. I will leave it to superior gun nuts to explain why this is a dumb choice of personal sidearm, but seriously, it's dumb.
Ruger .300 Winchester Magnum rifle, "Yoko"

This is, to my admittedly limited eye, a Ruger Precision Rifle. Not super expensive as this sort of thing goes, about two grand and change before you get spendy with the optics and other accessories. He presumably spent extra for the .300 Win Mag because .308 doesn't make his balls feel big enough.
