Yes, but this is nothing new. All those revolvers back in the day before semi-automatics were widely carried, none of them had safeties either.
Now some semi-automatic pistols have external safeties, it boils down to the design and the trigger. Pistol triggers come in two main types - single action and double action. In most guns you have a hammer with a firing pin or that hits a firing pin which hits the primer, firing the bullet. A single action means you have to manually cock it, and pulling the trigger causes the hammer to fire. Double action will cock the hammer and then allow it to fall at the end of the pull.
So old cowboy revolver guns, the venerable 1911, and most hammer fired semiautomatics like say a Sig P226 or CZ-75 are all single action. A semiautomatic like this will usually have a safety. Revolvers will not.
Things like old and new revolvers from Smith and Wesson or Colt, the kind used by police for decades, are typically double action. They can be cocked manually for a light, accurate shot, or cocked and fired with one long, heavy pull. They don’t have safeties.
Semi-automatics can have both options as well, firing in single action, or having the hammer decocked and firing in a long, double action pull, like the Army’s M-9/Beretta F92. These will typically have a safety option.
Glocks and the myriad of similar guns us a slightly different method and are called “striker fired”. There is no single action option, just double action. Instead of a hammer they have an internal striker that hits the primer. The trigger as it is pulled cocks the striker fully and lowers the striker block, allowing it to fire. They can be more safe in drop incidents, as a gun with a hammer can sometimes fire if dropped and hitting the hammer just right (old cowboy guns had no safety measure to prevent this, thus when you rode with one, you kept one chamber empty.) But due to the longer pull, and the drop safe nature, most of these guns lack safeties. There are some models like the S&W M&P that have it as an option, and I think there is an after market kit a gunsmith can install on a Glock, but in most cases they both lack safeties and generally aren’t seen as needing one, though they require a bit more caution.
(Note safety or no, NEVER have the gun pointing at someone, and never have your finger on the trigger unless ready to fire.)
Yep - other than the really old designs that were not safe to do so, most people who carry, carry one in the barrel. This is done by millions of people safely everyday, even criminals. The call it “Israeli-Carry” if you don’t carry in the chamber, as the Israeli police used to carry this way (not sure if that is still the case). This is why it is important to have a good holster that keeps everything properly orientated as well.
Yep - certain things you shouldn’t be doing when carrying. Though Federal and State/Local police almost always have exceptions to where one can and cannot carry. Even in “restricted” areas it is reduced to a slap on the wrist even if it isn’t technically legal. Some animals are more specials.
State laws on civilians carrying in bars vary, but even then I don’t know of any that allow drinking. But given this guy is an FBI agent, the worst that will happen is some shit desk job for awhile, probably. Worst case he loses his job. If he gets charged I will be gobsmacked, because some animals are more special.
