Heavy trigger on 1914 DWM Police 9mm

[DonVoigt]

Be sure the sear bar returns to its full "at rest" position.
Your trigger mods can result in partial sear engagement and the chance of doubling or more firing with a single pull.

If the sear does not fully engage the striker, it may slip off with minimal or no touch of the trigger.

While you are testing I suggest you load only 2 rounds in the magazine when firing live ammo.
