Looks like the folks at Doubletap Ammo finally brought one out. Prior to this, the only round that came even close to the original Norma-spec loads was Winchester's 175 grain Silvertip:

180 grain, 1350 fps from a stock Glock 20. Not too shabby at all!
They also have a 180 grain Gold Dot (1300 fps) as well:
