If caliber is removed as a factor, which very small guns do you recommend for ‘at least carrying something’, feeling lazy ccw days?

i’ve heard that calibers weaker than 9mm have reliability issues and also issues with effectiveness.but if we remove caliber from the discussion, which specific makes and models are solid choices for super lazy easy to conceal days?basically for days when your clothes, weather, or location might make it tougher to conceal a mid to full gun.or you’re feeling extremely lazy and just running to the store down the street (or getting your mail)carrying a tiny, less reliable, underpowered, harder to shoot for accuracy gun...better than nothingwhich guns would be good options? via /r/CCW https://ift.tt/2BMZQp4
