For OWB I have run CompTac holsters for a 1911, 226 and an fn45 tac and have really loved their profile and retention. I tossed their belt mount and tacked it onto a safariland mount. Never looked back.
I do have a few crossbreed holsters myself. The three main ones I use are:
Crossbreed Supertuck for my Springfield XDM Compact (I would call this my summer carry) My only complaint that I have is that the screw on the jclip comes loose semi often and I have to re-tighten it for fear of losing it.
Crossbreed Mini Tuck for my Taurus 709 Slim (Only time i really wear this is when I have to dress up a bit)
Galco Miami Classic II Shoulder Rig (I wear this mostly in the winter, especially since I can carry a flashlight in one of the mag pouches)
all day. You
