First, I'm not knocking any of the Police Officers working for the VA or any other GS-0083 federal Police Officers.
I did work for the VA as a Police Officer (GS-0083) and was there for only 7 months back in the mid 90s before moving on to a better paying federal LEO position with better benefits (Retirement/Take-Home vehicle). It's pretty sad, but at this point, VA police officers and many other GS-0083 Police Officers are not C6 covered LEOs, so there is no 20 year retirement plan for them. Again, IMHO, this is very wrong.
Also, they tend to hire "Police Officers" at the pay grades of GS-4 thru GS-6 and Sergeants at GS-7... Most of the new hires are picked up at GS-6.
Due to the lack of a 20 year LEO retirement and the low LEO pay, that motivated me to seek out a C6 LEO position. The good thing about the VA is that there are chances to advance up within the Police Service field up to "Chief" which I believe is a GS-11 position... "I" could be wrong with the GS grade, but its something like that.
I should note that the VA-OIG Special Agents/Criminal Investigators (GS-1811) are C6 covered officers with full federal LEO benefits, including the 25% Law Enforcement Availability Pay.
The daily job wasn't too demanding, but it had its moments when you are faced with an issue that may require you to make a physical arrest of an individual who doesn't recognize your lawful authority... Often during the arrest, they will tell you to call a "real" cop, but once under arrest and the facts are sinking in, their tune quickly changes. "I" had more problems with the hospital staff than the veterans and/or their family members. The doctors and many of the administrators saw themselves as gods within the gates of the VA medical center. Basically, you are seen more as a security guards than a law enforcement officer by the rest of the staff, until you have to arrest one of them for whatever reason(s)... Then be prepare for a visit by the union's shop steward about the arrest.
BTW, I worked at one of the medical centers in the New York/ New Jersey area. With that being said, it was a difficult area to work and most of the officers where actively looking for other LEO positions, local, State and federal. They had a problem retaining the better officers who often resigned from that position within 6 months to a year for a better paying LEO position. AGAIN!! This was the NY/NJ area!!
To my current understanding, the VA administrators, like other non-law enforcement administrators within a non-law enforcement agency are not supporting the ideal of their sworn law enforcement officers carrying firearms off duty... The thought being "If I can't carry, why should you?" ANYWAY!! That has been corrected with the passing of the Law Enforcement Officer's Safety Act of 2004, which allows you as a sworn and armed LEO, with agency issued I.D., to lawfully carry a concealed firearm off-duty... With some restrictions. Furthermore, the LEOSA-2004 doesn't grant you any expanded authority outside of your jurisdiction on the VA's property... Basically, the act is for self-defense and I'm pretty sure that the VA administration will make it very clear that you are "legally" on your own while off-duty if you choose to carry off-duty. I'm not sure, but I "believe" that your issued duty firearm is lock up on VA property after your shift has ended. If you should decide to carry off-duty, "I" would carry the SAME model, SAME finish and SAME caliber pistol that you carry while on-duty WITHOUT any modifications whatsoever... Just in case you are involved in a shooting, you can point out that you are qualified with the SAME type of firearm for your official duties as a VA police officer. I'm a retired federal LEO (GS-1811) with over 21 years of service and was issued an I.D. card from my former agency identifying me a retired agent that meets the standard(s) of the LEOSA-2004. "I" decided to carry the same pistol that I carried as a back-up pistol when I was working, which was recorded by my former agency and with records of my qualifications scores on file... Just in case!!
I should note that under the LEOSA-2004, it doesn't state anything about the type of handgun that you may or may not carry, but a little common sense must be used... Technically, by the spirit of the law, there is nothing stopping you from carrying an AR or AK pistol, "BUT!!" Why put yourself into a situation that may involve you putting up your own cash to resolve it and/or having your employer looking at you in a less than a professional manner. There have been some issues in New York City involving LEOSA-2004, but nothing is an issue until it becomes an issue.
IMHO, if you have another choice for a LEO career, I would investigate it... If not, I would take it and learn everything you can, so if you decide to leave, you have something to offer your next employer.
Good luck!!
