I have 1500+ rounds through my 9mm Shield and not one failure. No light strike, no jams, nothing. 7+1 or 8+1, depending on the mag I carry.
I'm not going to spend more money for another gun and more money for ammo just so I can carry an extra 3 rounds.
More generally, I have what I need for now. I've been on the "buy the latest and greatest" merry-go-round before, and all it does (for me) is leave me unsatisfied, as I'm always "looking for more" and in the "Oh, if I had only waited until *THIS* gun was released" mode of regret.
I carry either a J-frame, a Shield, or a 1911. Each is proven and I practice with each regularly.
I understand the allure of the P365, and new guns in general. But at some point I just stopped buying the latest and greatest. Funny thing is all of my recent purchases are the "old school" 1911s.
If others enjoy getting a new carry gun and shooting the heck out of it for a year or two until the next new thing comes along, then that is great for them and I have no problem with their practice. Do what you enjoy doing. It's just not for me.
