It’s mostly about personal trial and error.
For range guns I can live with a light strike if it’s rare.
Depending on gun condition and setup, ammo and also the shooter.
Many malfunctions happen due to the way the shooter is gripping and running the gun.
For service, EDC and home protection I personally wouldn’t even use the PX4 D spring.. Stock is great and when adrenaline is pumping a 20Lb spring can feel like 5.
