Ive noticed curious thing in my new px4.
When i rack the slide and the trigger is in the SA, there is slight, tiny pre travel, like 1-2mm, and when i pull the trigger, the gun is making some weird scratching noises.After i go past through these 2mm, if i release trigger it wont get back, and there will be no additional pre travel and no noise next time i pull the trigger until i rack the slide again.
It also aint happening when i pull the hammer to SA after decocking the gun.
Is it normal? Or, am i even comprehensible?
