G17 Front Sight Height for DP Pro?

Ok, so. I've got a Gen 4 G17, Leupold Deltapoint Pro, and Deltapoint Pro Rear Iron Sight. The slide will be milled for the DP Pro. I need to pick up a front sight post that will allow me to co-witness. I've seen lots of people talking about front sights being too low to co-witness since the DP Pro is taller. Any suggestions on a front sight post that WILL be tall enough to co-witness on this setup? Thanks in advance!

I would call Dawson and ask... I have a DPP on my Sig X-five with the add-on rear sight and I had to go with a .400" tall front sight. They knew exactly what I needed and hooked me up.

Awesome, thanks for the input!
