I've been on here reading for a while about the XD's. I'm getting one within the next week or so. Every time I'm sure about what caliber/size I change my mind. So I figured I'd put up a poll for some additional advice. I'm going to be using the XD for home defense and a range gun. I'm leaning toward the XD-9 Service for the cheaper ammo and I know with todays ammo it can be (arguably) just as potent as any other caliber. But the Tactical would suit my purposes as a range gun too. I probably won't be carrying and if I do I'll pick up a sc down the road. .40 and 45acp are also in the picture and I know about the barrel swaps you can do with the .40. So knowing alot of the pro's and cons have me doing a constant flip flop. Any help/advice is appriciated.
