OK, I'll fess up. My EDC's are Kel Tec's because they are inexpensive - they are the Bic pens of the handgun world. In my pocket and in my vehicle they get scratched up and bumped around, and I don't care if they do. The EDC's are maintained and shot regularly to ensure reliability, though.
I'll also admit I'm a cheapskate. I have a bunch of firearms, over 30, but none are safe queens; they're all shooters. My most expensive ones may have a value of $800. Even so, an EDC is a tool. It has to be reliable, but I don't carry it to impress anyone. Therefore I use tools for EDC that I don't mind wearing out, or breaking, or - if ever used in self defense- surrendering to LE during the legal process.
