NOT KNOWN FACTUAL STATEMENTS ABOUT GLOCK 30 GEN 4

My next G30SF also had precision concerns and also the WORST trigger pull of ANY Glock I've ever owned, and I couldn't appropriate it using this setup whatever I did and effectively over 1,000 rounds of attempting to resolve it and “crack in” the gun (which I have NEVER had to do with any Glock before both).Is one a tiny bit far more trusted?
