How strong would recoil be for a relatively experienced user using a pistol at close-range? also, does a gun’s safety actually exist? like, if you hid a gun in a bag for protection purposes, would that be a bad idea?

First off, range has nothing to do with recoil. Recoil is something the gun does every time it’s fired. It can not tell if it’s being fired at something three inches from the barrel or something on the dark side of the moon.

Second, recoil is affected by stance. If you’re holding the gun correctly, and it’s not some massively overpowered weapon, like a S&W .500, recoil is not going to be significant. Recoil tends to be stronger with shorter barrels.

Safeties are real, but they’re specific to an individual firearm. So, if you’re looking at safeties being reported in different places, it’s probably just different guns. I have handled firearms that didn’t have any safeties, but these are something of a rarity.

Manual safeties are physical locks that prevent the gun from firing and are set by the user. When you use the term “safety’s on” or “safety’s off”, this is the kind you’re talking about.

Integral safeties are internal mechanisms designed to prevent the gun from being fired accidentally. These vary wildly, but can include pressure plates or locking mechanisms that engage automatically when it’s held correctly. (There’s actually some inconsistency in the terminology, if you see something called a grip or automatic safety, it’s one of these.)

Finally, single action firearms function as a safety in some firearms. Single and double action refers to behavior with the hammer. In a double action weapon, pulling the trigger will cock the hammer, in a single action, it won’t, and if the hammer isn’t cocked, the gun cannot be fired. With all automatics, the slide will reset the hammer when it cycles. But, a single action automatic cannot be fired if it’s not cocked. With single action automatics, a decocking lever can function as a safety.

Now, as I said earlier, safeties are very specific. The 1911 has all three; a manual safety on the left side of the slide at the rear of the pistol, it has a pressure plate built into the back of the grip, and it’s a single action. But, that’s far from the norm.

I’ve also seen integrated safeties in the trigger itself, (the Glock and S&W Sigma have this, also I think the P99). As I recall, the Springfield XD actually has one on the trigger and a backstrap plate like the 1911.

Finally, carrying a handgun in anything other than a gun case or a holster is a bad idea. It doesn’t stop people from doing it, but, like sticking a gun under a pillow, it’s one of those things that make me shudder.
