You asked a question that defines why I despise caliber snobs....
caliber snobs, don't bash me. I agree that More Power ='s better, as long as all other parameters are equal. For everyone that tries to convince others that they need no less than a .45 (or .40, or 9mm) for CCW, I cringe because that individual may well get very tired of carrying a bulky firearm very quickly. Own what is comfortable and you KNOW FOR FACT that you will carry.
With that said, if you carry that .45 every single day, then good for you. You've got one up on me. I'm lazy, and will not carry that .45 every day. SOOOOO... I have a little .32. I have a very capable 9mm BDE that conceals well enough, but isn't very comfortable. I carry it some days, or if I'm going somewhere I'm not comfortable going. Most of the time, it's the little Astra in .32 that I can stick IWB, in the pocket, or wherever else is comfortable.
