Have the Romeo X Compact on my P365 380 with the top 1/3 of the standard irons for cowitness. My Hellcat OSP has the Shield RMSc with 100% cowitness of the standard irons. Both have been flawless so far and deserve a look. The Romeo X allows battery change without removal of the optic and the Shield RMSc requires removal for a battery change. My Shield 9 1.0 came with a CT801G green laser/light. I replaced the stock white dot irons with TruGlo Tritium Pro Night sights but don't feel a need for a red dot on that one yet. Good luck with your search!
