.380 9mm difference

I have had the same few guns in each of these for several years. I probably have run somewhere between 7,500 and 10,000 rounds through my 9mm (FS 92) and maybe 5,000 though one of the .380's (Makarov)*and less then 1,000 though the other (BDA .380). Of course we know the .380 and the 9mm...
