I have the very same setup on my 17, but with the rmr06. The Vogel puts the OEM trigger to shame.UPDATE (long over due):
So for me and my intended uses(s) which are general range training/prioficentcy/fun and OWB carry with a BH Serpa Holster. I've nailed it down after trying a few different red dots, Dawson and Trijicon Suppressor Sights. The winners are RMR07, Vogel Comp Trigger at 3.5lbs and the Trijicon Suppressor Sights. For me I want to be able to cowitness irons and optic. 1. I acquire the dot much much faster to put it on target. 2. If the dot fails in a situation I am not SOL.
