I used to do a drill with my nephews. You, the safety spotter, take the weapon and either load it with one or none. Hand it back, (remembering that the weapon and range are hot) and have them shoot. You can than watch the trigger pull, especially on the dry fires.

But remember this is done on the line and the weapon, when returned to the shooter will be locked with the hammer cocked.

It really helps. revolvers are even easier.

Use the BRASS method. Breath, Relax, Aim, Slack, Squeeze.

And another thing to consider, it is not speed, but Rhythm, Think Shooter Rhythm.
