I carry both revolvers and SA pistols. The key words to remember when using a SA is DAO and/or safety. I agree that cock and lock is very dangerous. Also always perform a thorough careful inspection of the chamber when clearing the weapon. The next best bit of advice to anyone is to practice proper gun safety 100% of the time.
I disagree, particularly on the 1911 platform.
Glocks don’t have a traditional safety. You best safety is the three pound, shoulder mounted computer.
