So let me get this right. . . You carry a 1911 but you don't know what sort of 1911 it is?  You back it up w/ a .38 snub, carry an LG cell phone and a Blackberry, two locking folding knives, two multi-tools, an excellent Surefire and a very good LED b/u light, and you want to know what to carry in your empty pocket.  Sure, get an   
Ultralight .5 First Aid Kit from Adventure Medical Kits.  If you have room for a back-up get a   
Wound Closure Kit too.   
So is this 1911 government issue?
