We all want the best training. It can be expensive if you are having to pay for it and it can be hard to find the time to do it. There is a whole lot of BS out there. What can you do? First, pistol handling is not rocket surgery. If you will learn the basics and practice on your own you can be fine. Smooth draw, quick pairs, reload. If you know those things well you can be OK.
I know a young man who shot down two hold up men in 2010 at very close range while he and his GF were walking home from the store. He in Wyatt Earp like fashion ignored the fire coming from the gunman and killed him and wounded his accomplice. He nor his GF were injured.
He like many was willing to give them the money until he picked up on nonverbal cues that because of his GF they were not quite satisfied with the money. He had a Glock 27.
He had only the most basic of training in gun handling but did do some draws and some dry fire a couple times a week and live fired maybe once a month. That basic skill combined with knowing what to do was enough.
He shot at the first possible moment despite having let the guys get the drop on them. When the gunman turned his head because a car drove by that was the opening. A split second is a long time sometimes.
Work on some one hand shooting at close range. That is a skill not as popular as it once was and you want to use two hands when you can. Often you can find yourself doing something with your off hand though so be able to shoot with one hand out to 5 yards or so.
