Go through this thread... there's a really comprehensive post on PJ gear.
In short - if my memory serves me correct - a rappelling harness (Black Diamond, Blackhawk), Paraclete HPC or RAV with Paraclete pouches, or Eagle Air rescue vest, even a few RRVs plus a few (To be honest quite many, actually) other rigs. First line... you can roll with or without a pistol but it seems like a good idea too have another GP/med pouch coz that's what PJs do.
For a real up to date kit, you'll want some Crye MC with MC gearz. Lotta good pics in the one link to mp.net.
Just don't forget
