There’s no manual safety to disengage on Glock handguns, a common standard issue sidearm.
They have safeties such as a split trigger, but they’re intended to stop negligent discharges. There’s no switch or button to turn it on and off a “safe” mode.
I may have misused the term, thanks. As far as the split trigger my understanding is that’s for cases where your finger or other object unintentionally partially pulls the trigger.
There’s an additional safety on glocks for drops where the firing pin is blocked by the trigger bar unless the trigger is pulled in a manner that satisfies the split trigger mechanism.
