Welcome to pistol-forum; you have come across one of the higher signal to noise ratio firearms-centered web sites there is, I believe. Great for you for wanting to improve.
A few questions?
What are you trying to achieve?
The more specificly you can answer that question, the more the experts here (I am not one) can help you get focused and headed in the right direction.
So for example, do you want to enhance your first shot accuracy from a concealed draw at 7 yards? Are you wanting to improve at competition scores in IDPA or USPSA? Do you want to improve on skills related to .mil or .leo tasks?
As a self-diagnosis, absent other objective measurements of where you are, have you shot or can you shoot 10 rounds at a NRA B-8 target at 10 yards in 10 seconds and post a picture of the target? That is a drill called "The Test". I use it as a barometer of where my skills are. I shoot it cold most every range session and find it is a good overall metric on my skills (or lack thereof lol) and ability to improve.
Another drill I shoot regularly is "Finding Your Level":

I went to the range for the first time in 2014; I suck at shooting but have been hanging around here for a few years and picked up a few things along the way. There are a lot of good threads here on the forum but it kind of depends on what you are looking for.
