Believe it or not:
a. You are a new shooter. I've shot "thousands of rounds through Glocks" in under a week, when you've shot tens of thousands or hundreds of throusands abd spent lots of time in formal training, competition, etc., then start considering yourself experienced..
B. Practice does not make perfect - only perfect practice makes perfect. There are people I have shot and trained with who have been regular, enthusiastic shooters for 30 years or more...but they never learned the fundamentals really well, so they will never be able to shoot.
You need to work on grip and trigger control, correctly.
"Liberal" is when you hire others to use a guns to protect you, so you can pretend guns aren't necessary.
