9 or 40, you are making a good decision w/ the tactical. I currently own 2 xd9 tac's and recently sold my first XD (also a xd9 tac) to my dad who was more than a little surprised at how well he shot it never having played w/ autos before. It is a very stable platform and if you are interested in competition at all, I would say 9. Reason for this is strictly finances. If you do nothing but shoot a local league, you will go through a case of ammo in 2-3 months. That price break on 9 vs 40 will be key to getting you out to the range to actually shoot the gun more too. Also, if you have friends/family you think you would like to get into shooting, the slightly tamer recoil from the 9 will be easier to use to introduce them to your new love, and if you decide later, you want the 40, you can always do like I did and sell your first 9mm to a good friend/family member and buy that purty new tactical in teh cal. of your choice.
The easy confidence with which I know another man's religion is folly teaches me to suspect that my own is also. I would not interfere with any one's religion, either to strengthen it or to weaken it. I am not able to believe one's religion can affect his hereafter one way or the other, no matter what that religion may be. But it may easily be a great comfort to him in this life--hence it is a valuable possession to him.
