1) Safeties can get you killed
2) Safeties are failure points. You can accidentally activate a safety, when you don't want it. Or forget to turn it off, when you don't want it on.
3)There is video evidence, multiple cases, on the YouTubes, proving point 1 and 2 above
4) I would never carry a gun with a safety. I've carried guns for 20+ years. Newsflash! They are completely safe fully chambered, ready to go, in a proper holster. They will never go off. Train properly, and you'll find that safeties are failure points. I don't want failure points on my guns. I want the trigger to get pressed, and a bang to happen. Simple. No failure points.
5) Carrying Israeli method sucks too. If this is your method, again, get more training.
6) If you are uncomfortable carrying a fully loaded, chambered, plastic fantastic pistol like an XD, Glock, P365, etc, then you haven't trained enough.
You can have differing opinions on the topic. I too, have opinions on the topic. Mine is based on my world view, experiences, and level of training. You have differing opinions, and that's fine. Your opinions are based on what you know.
The 1911 (and other guns) has a safety. And some guys like to carry them. That's fine. The gun isn't for me. I've tried them and put $50,000 worth of ammo down range in them. I can operate them reasonably well and usually without issue. BUT. On a range, with paper targets, I do on occasion forget the safety. Id be terrified to forget the safety in a real world event when I only have micro seconds to respond. And its not just me. I spent 2-3 days a week on a gun range for years doing firearms training and I SAW with my own eyes, guys forget to flip that safety lever, 10, 20 times a day. When you spend that much time on a gun range watching folks, you begin to pick up patterns and observations.
I would never recommend a pistol with a safety, for self defense, for any of my students.
You may have a differing opinion, and that's fine.
The military requiring a safety on its 1911, Beretta 92FS, and now Sig P320, actually kind of proves my argument. The pistol , in the military, is a secondary weapon and training is severely lacking across all services. They have always required a safety for lowest common denominator level of training that they are able to provide.
The British army issues the Glock 17. The American army issues the P320 with safety. The AVERAGE British soldier is also far better trained on pistols, than their American counterpart.
