I carry the same thing all the time.
Glock 19 on my right hip (Concealment Solutions Black Mamba IWB holster, recently switched from OWB)
Ruger LCR 38 SPL in DeSantis Pocket Holster, left pocket for backup.
No rotation, except when I "dress up" for special occasions, I'll carry my 1911 in a custom sharkskin OWB.
This eases training as I only have to be able to shoot two guns and I'm not searching for controls because I'm not used to carrying something. Lots of other guns for the range though.
