I haven't had those problems, but unfortunately not trouble free. My 42 had a greater than 8 lb trigger according to my gauge. Called Glock and they said "don't expect a 5.5 lb trigger". I said why is the case and all literature saying that then. Long story short I noticed the trigger bar was running outside (and on top) of the connector. After bending the connector a little bit at a time the trigger bar is now being held in place and trigger pull measuring 7 lb on my gauge.
