I have pondered this and tried many varieations for the last 18 years years. My duty Pistol is a Colt 1991A1. Off duty I have tried just about everything from Walther PPK, Colt officers model, Glock 23 and 27, Beretta Tomcat, Smith model 60, Back to a Walther ppk/s, and I sold them all to carry the 1991A1 all the time. Problem is it didn't work out that way. You see, the Colt, while the best handgun ever invented, is heavy. Fine in a duty rig or occaisional carry, but over time and with Age I noticed that when I got home from work, it went into the gundrawer only to be taken out for next months reserve stint. As an Active reserve officer I am fully authorized, but no longer required to carry off duty. I had simply stopped doing so. I finally settled on a Taurus 85 Titanium model. It is reasonably compact, it is certainly lighter than all but the beretta Tomcat and thats debateable, and it packs a serious punch with .38+P. It has become my always gun. Now, I no longer ride alone.
