I handle the LEM trigger much as a double action revolver.
A straight, efficient pull, rather than a long, drawn out ordeal.
Somewhat quick, but never jerky.
I don't worry about the wall, or finding the exact point of fire.
I just pull back smoothly, and the gun goes off.
I shoot the P30 LEM much like the VP9, and every bit as well.
This style won't work for everyone, but it works for me.
