I've done several defensive pistol courses at Sig Academy in NH, and always chose a P229 when there--and had pretty much my pick of anything in the armory, which was a lot. It's a fantastic handgun, no question. The idea above of an X-Five in 10 is pretty cool, too...it would certainly be a beautiful piece.
But, now that I've got my EAA Hunter and have a few rounds through it, I'm sold for the time being on that gun. With 15 in the handle, a grip that's as comfy for me as any super custom 1911, and no plastic to be found anywhere...I'd buy a 2nd one or the EAA Bullseye model before going any other route if it was a high-performance target-length gun I was after having rock-solid build. IMO, they're built and machined like the old Belgian-made Brownings of yesteryear, or as close as you can get for under $1,200.
