I'm only able to get through all of the comments right now, but I had seen that someone else mentioning reputable instructors coming out to the range for some one-on-one and you better believe I'll take advantage of it. I also just did a few drawing from concealment drills and I think i figured out why some are not fans of the finger grooves on Gen 3/Gen 4 Glocks. I love my 19, but I found it difficult to rapidly get a steady grip, to their credit this is my first time practicing that maneuver.You can practice drawing from concealment, focusing on your front sight and target acquisition, and magazine changes without ever leaving your house. It's no substitute for actual live fire training and recoil mitigation, but it's an invaluable training tool. I would look to the local gun ranges in the area and see what type of fundamental classes are offered. At the very least, it may allow you to draw and fire from concealment. I would also look to see if any ranges in your area host guest instructors. A lot of the reputable, big name industry instructors travel to teach.
Hope you and your family are safe, @Kinzei. Texas has been in my prayers.
