Now that I have managed to obtain a supply of 95-grain Winchester Ranger® T Series ammunition in .380 ACP, I find myself frequently carrying my venerable NAA Guardian .380 as a backup to my Rohrbaugh R9.  The R9 is carried in the strong-side front pocket and the G-380 in the back pocket.  Today both are in Hedley holsters.  
I might add that neither of these two pistols has ever displayed any vices.  That is rather comforting to me.
