Where did you get that information? I have several friends (former colleagues) who were in that program, and the ONLY authorized weapon was the issue P229 in .357 SIG caliber.
They could not even carry a back-up gun, much less have a choice about what to carry for a primary.
If you're thinking about the FFDO (armed pilot) deal, they must use the issue HK USP Compact in .40 S&W. Got a couple of pals still active in that program.
I'm not "calling you out"; just curious. My information IS a bit dated, and they might have changed the rules... but somehow, I just cannot see the feds authorizing a Ruger P-series...

No prob, LSP.....I got it from their website. I'm om my iPhone right now....I'll be home in a few and get you the link.....

(BTW- I know what you mean about the .357 Sig, cause I was told the same thing.....)
