I was wondering if anyone has noticed a difference in accuracy between the two? For some reason my XD9 seems to be more accurate than my HS2K. The XD is stock but the HS has Don's guide rod with a 22# spring. I will switch back to the stock captred rod and see how the accuracy is. It may be the 22# spring is too much for a 9mm. Both of these guns are in 9mm.
