Hello Dawn, still new to this community but I’ll weigh in on this. For over 20 years my EDC weapon was a J frame S&W 640, .357. I absolutely love my little snubby and the power of the .357. However with the information age smack in my face and U-tube channels like Active self protection, I have come to the realization that 5 rounds might not be enough? Both of the newest weapons, the 365 and the Hellcat hold considerably more rounds and both are almost equal in size to my revolver. Their actually thinner. And for someone of my build very concealable. As far as more confidence I would say no! For the same issues you mention. More rounds doesn’t translate to better Unless the shooters skills and mindset translate to being more aware of every aspect of a self defense shooting. Further, I can run just about any firearm put before me but my trust will always remain more grounded with my revolver. However I do find some slight security in the knowledge that, if facing a situation with multiple assailants the fact that I have 12 or 13 rounds is most definitely a comfort, not to mention that I’ve begun carrying a spare magazine. The Hellcat was my choice but after firing the 365 as well. I feel either weapon would/will fit the bill nicely with each having pros and cons for me.
