I have several guns I rotate and carry depending on how I am dressed but after picking up an LCP a few months ago I carry it all the time. In a raven pocket holster or an IWB I picked up from a local leather guy at a gun show, it's just carries so easily. Until it started warming up I almost always had a second(primary) gun on me but now that its cargo shorts and tees weather I feel pretty good carrying it alone.
They say most confrontations occurred inside 10 feet and I think this caliber is perfect for this situation. The zombie max was all the self defense my LGS had when I bought the gun so that's what's in it but once I find some +p then ill make the switch.
Hell if one shot doesn't stop him I've still got five more...
