where'd you get those night sights??!!!

i'm getting ready to walk out the door on my way to my dealer to get this same gun! saw it yesterday for the first time and i'm in love! i'm no newbie to concealed carry or concealed carry guns. i'm a from-way-back glock guy that's about to swap a g19 for one of these.
this gun, to me, is the quentisential ccw piece!!

Meprolight has the sights on stock.
