THE 5-SECOND TRICK FOR GLOCK 30 GEN 4

My next G30SF also had precision issues and also the WORST set off pull of ANY Glock I've ever owned, and I could NOT proper it working with this setup regardless of what I did and well around 1,000 rounds of endeavoring to correct it and “break in” the gun (which I have NEVER had to do with any Glock prior to both).Potentially a dumb question,
