Welcome. I have to agree with mlmiller1, as you make that Glock more and more “Competition ready”, prep yourself for the issues. I have had and currently have a 34 open gun that now runs flawlessly. But it didn’t just happen. Tons of work and troubleshooting with each little change.
my suggestion would be to start with a full drop in trigger to get the bounce and springy feeling out of it.
adding weight to it isn’t a bad idea, just do one thing at a time and shoot, shoot and shoot some more
