Many guns are manufactured and sold without safeties. Personal responsibility transcends industry.
Fun fact: one of the bartenders at my old watering hole was playing with the "bar gun", flipping the cylinder closed by flicking his wrist, and shot a round into the wall. Luckily I wasn't there that night because accidental discharges are a beatable offence.
If someone shot a round into a wall at a bar, it would be more than a beatable offence for me.
The two most popular handgun lines in the US, the Glock[1] and the M&P[2], don't have what a laymen would consider a safety. The Sig P250[3], of CounterStrike fame, has no safety of any kind whatsoever.

(You should NEVER put your finger on a gun's trigger unless you intend to fire it. This is taught in all good gun safety courses.)
I doubt the original commenter new the difference, and was most likely referring to manual safeties.
There's internal safeties to stop it from discharging if you drop it, but there's no safety to stop you from pulling the trigger and discharging a round.
