My understanding is that the 357 sig round was developed specifically for the FBI to penetrate barriers like car doors. This also translates into over penetration in human tissue making it less effective for self defense than many other rounds. The problem is that most people buy what they think is cool and if the FBI uses it then if must be for me too right?:tongue:

The .40 was developed for the FBI after the Miami Day shootout not the .357 sig. The .357 Sig actually fragments on impact. While they do make armor piercing rounds for it. Its used by Air Marshalls on airplanes where there cant be much overpenetration.. It has More stopping power then the .40 but less recoil. The 357. Sig is a Great round that is under appreciated in my opinion. SIG's 40 cal P226 can shoot .357 sig with just changing the barrel. 2 rounds in one gun :biggrin:
Back on Topic. The XD is a Great Firearm Especially for the price. I havent fired one but have held them. They fit comfortably in my hand. But I generally stay away from polymer guns. But to each their own. Have you considered a SIG? :wink:
