When a gun of mine has been to the factory twice, they will never see it again, and neither will I.
However, I learned long ago that many aggravating little problems have simple solutions done at home. These work, and there is no reason not to follow the advice of others who have been successful with minor adjustments/repairs.
Stubbornness and pride have a cost in time, effort, frustration and aggravation. I won’t spend that capital on a $400 machine. If this thing otherwise works as it should, and cutting a little spring seems to be the fix, and you won’t do that, you are making your own problem worse.
Cut the spring.
