If you're interested in a particular brand, just email the company and ask. Glock, for example, extends its Blue Label program to "District Attorneys." Even though that's not my title (Arkansas doesn't have anybody called a "district attorney"), and told them that I am authorized to prosecute felonies in my judicial district. Without hesitation, they sent me all of the materials. IOW, even if your title isn't listed, the company can still include you in the pricing program based on your job description.
I'm a lawyer, but I'm not your lawyer. If you need some honest-to-goodness legal advice, go buy some.
