Opinion: What's the BEST Handgun Cartridge/Firearm for Carry

Please realize that the first word of the title is "opinion", and not some sort of an expert statement as I may not be an expert in your particular field. But for me, and what I think would be best for a lot of people, I am giving my opinion of what I think the best handgun cartridge and handgun style for concealed carry. This opinion is based on my personal experience and this video is more of a basic rundown of some positive attributes to my opinion. Always appreciative of any channel help :) https://www.patreon.com/user?u=5828221
