There are at least some of us who do carry a .45 everyday. I would venture to guess that there are many who do. When I am not carrying that, it's the .357 640-1 that's in my pocket as we speak.....er.... type.
I prefer a .45 over anything else in general, but it's not always practical. I do not feel undergunned with the .357. Having said that, I would never belittle anyone for carrying whatever they felt comfortable carrying. I have my preferences, and others have theirs.
