I'm sure the leaf spring sits properly as shown in Troubleshooting Q2A2.
Once I change it back to stock leaf spring, everything back to normal.
so why it only happen on light weight leaf spring????
The ILLusion Kinetics / Airsoft Surgeon Light Weight Leaf Spring is meant to be adjustable, and out of the package, is tuned for a very light sear pull.

If the fitment of your sear does not allow for restriction-free movement, the light weight of the leaf spring may not have enough force to move the sear fast enough to engage the hammer.
If this is the case, you must bend the middle (sear) prong forward a bit to apply more tension.
