If you like the Warrens with the f.o. front, carry it.
Absolutely nothing wrong with it. It'll be protected in your holster 99.9% of the time anyway. If the little f.o. does happen to fall out when you get into a gunfight, you still have a great set of plain black iron sights.
I carry with plain black sights.
