Yeah, The DPPro is a tank, but incredibly rugged. Great for the nightstand, range, or suppressor, but not holster-able with that post up there. To get it to co-witness properly with the DP rear iron I needed a .440 tall custom made tritium from Dawson. $59.
I'm having my other P-07 SR milled at Primary right now for a Venom, hoping the stock SR front will co-witness as-is.
Really though, I'm getting so used to presenting the RDS and find I don't reference the front sight anymore. It's there in case the RDS goes out, which never happens.
Probably the best milled-in RDS carry-option right now is the very low profile Viper, but I had the DPPro and Venom already.
