JJ with gun

[fullmetaljackie.livejournal.com]

anyone know which episode is the one where jj busts into a room somewhere with a gun? i think she also has a f.b.i. bullet proof vest on and she looks very sweet even with a gun. :0) i was thinking it was at the end of the second season like maybe 9 10 11 or 12 but so far i am unable to find it at any of the screencap sites so maybe i am off.

also i think i remember it being a glock pistol but does anyone know what kind of gun she carries?
