Also forgot to mention in PM that the Web will have a large number of gun cleaning videos available for your review, such that you'll never need to attend a class or demonstration if you don't wish to do so.
Just Google "cleaning a Glock 23" or whatever specific handgun you wish to clean.
You'll get hits.
One point to understand early in the game is that there are many favorite methods, tools, solvents, cleaners, sprays, brushes, lubricants, etc. employed by various shooters. Most all of them work. Some shooters are very dedicated to their own particular cleaning, lubricating, and storage methods and will argue that their particular method is The Best. They are correct. It is the best method for them.
You will develop your own techniques as you move along.
