Get one. But you'll need to practice with it a lot. Like said above, there is a big learning curve. I've used Burris FF IIs and IIIs and Trijicon RMRs. My Newest Glock G17 Gen 5 wears a Trijicon Dual Illuminated RMR. I started off hating it but love it now and like it better than any red dot RMR's I've tried. I am still not has fast with this gun as a I am with my G19 Gen 4 with XS DXTs sights, but I am more accurate with it. On a defensive handgun, up close, I am not sure it matters much is you have a red dot or good iron sights. At longer distances, a dot sight has the accuracy advantage.
