At first I was a little scared that I made the wrong decision on getting the 3" XD-9. I was worried I wouldn't be able to hit the broad side of a barn with such a short barrel. I went back and forth for a couple months and almost gave myself an ulcer trying to decide. :banghead: I needed a good reliable CCW pistol, which is why I went with the sub-compact.
Thankfully I was very surprised that I actually shot my 3" XD-9 the same (if not a little better) than my friends 4" XD-9. I would say the 3" is every bit as accurate as the 4".
It has been said before (which I now agree with) that the best way to go is to get both the 5" Tactical and the 3" sub-compact. With the 4" service model you don’t get the benefits of the longer sight radius of the Tactical, and you loose the conceal ability of the sub-compact. Go with whatever your needs are... Either go with a big range pistol (5”), or a smaller, more concealable CCW (3”) pistol... Or better yet, get BOTH! Which is what I plan on doing down the road.
