I checked the Speer manual, and based on their tests with Gold Dots, the Sig shades the best .40 in muzzle energy by 10%. I'll get the drop-in barrel for my Glock 23 and try it myself...if I can find a barrel, and dies, and bullets, and powder. At least I have primers. And I guess I need to buy a 4" .357 Mag to compare...right?
