Striker-fired Pistols
It is good to replay a periodic warning about the critical need to keep your finger off the trigger and out of the trigger guard when using a striker-fired pistol.
You may be able to safely get by with 'caressing the trigger' on a double-action revolver, but that is NOT a safe thing to do with a striker-fired pistol. There have been many accidental discharges due to the failure to keep fingers, and all other objects, away from the trigger until intentioned to shoot. The problem is addressed in training by intensively teaching students to keep their finger out of the trigger guard until ready to shoot — no matter what kind of gun you are using. It is critical that the shooter do that when using a striker-fired pistol.
The following video shows a striker-fired pistol in cutaway. Note how it differs from a conventional hammer/firing pin action.
Of course, it's wise to constantly review and practice all of the safety rules.
