Title 18 350 provides for the on dutyquote where it grants you the right to carry concealed weapons both on and off duty.The rules & regulations the AG prescribes are that an employee is required to attend weapons training and work posts that require the use of a weapon unless you are a chaplain or a PHS employee detailed to the Bureau of Prisons. In order to provide the cite for that I'd have to dig around in the hiring paperwork and that would take a long while, just trust me on that one. We are required to be able carry a weapon on duty. Concealed though is not part of it. We carry like street cops do, on a holster on our hip or an AR15 slung over our shoulder.Officers and employees of the said Bureau of Prisons may carry firearms under such rules and regulations as the Attorney General may prescribe.
Title 18 926B provides for the off duty concealedWe meet all qualifications of subsection (b).(a) Notwithstanding any other provision of the law of any State or any political subdivision thereof, an individual who is a qualified law enforcement officer and who is carrying the identification required by subsection (d) may carry a concealed firearm that has been shipped or transported in interstate or foreign commerce, subject to subsection (b).
I didn't make up the name for that section. PS 5510.12 has the prohibition. If you open the PDF it is on page 4. Here is a link directly to 5510.12.as I said, the section you took that rule from is titled: Inmate and Custody Management
That would infer that any rule in that section dealt with inmates, not employees. I did not see what you posted in the section to be able to determine the context of the statement. If you want to take something out of contrext and utilize it, I can prove there are men on mars as stated by NASA. You need more than a snippet and I'm not hunting for it.
In regards to the possessing vs carrying. The policies prohibit simply having a weapon in your vehicle. They can search your vehicles. Refusal to consent to a search requires that you leave the premises. If you are employed, you will most likely loose your job (it's been attempted once to my knowledge and I believe the employee regained their job after he brought sued the Bureau). See PS 5510.12 page 7 for the entirety of this quote:I hope I was specific enough. If anything else is still unclear, let me know and I'll quote/post anything you need for reference. I've attempted to only quote relevant sections of each PS or Code since it would take up a massive amount of space to copy the entire PS/Code.You are prohibited from engaging in prohibited activities

Bureau facilities, without the knowledge and consent of
the warden. Violators may be detained or arrested for
possible criminal prosecution, either by Bureau staff, or
