From what I've seen in IDPA, most of the "serious" competitors use the dawson front. I'm running an XDm right now with the factory sites, I used to have an XD with the Dawson front/rear, but it stayed on the gun when I traded it off to get an XDM Compact. I miss it, and hopefully Santa will be real nice this year with an XDM 5.25" for next year's IDPA season.
