Can anyone take your classes? Students have to be at least 18 years of age and not prohibited from possession of a firearm by federal or state law. This generally means you must not be a convicted felon, not have been adjudicated mentally incompetent or be under a court protective order. I welcome students younger than 18 if, in my judgment, they have the maturity to handle firearms and the attention span to learn from my classes, though students under 18 must be accompanied for the duration of the class by a parent or legal guardian.
What kind of firearm will I use in your class? I can provide firearms from my own small collection so there is not a lot of variety although it does include semi-automatic pistols and revolvers. I often assign new shooters something in .22 caliber, but can make special arrangements to have a particular type or caliber available if a student requests it.
If I bring a firearm to your class, does it have to be registered? In a word, NO! Thankfully there is still no registration of firearms in most states. Only the citizens of New York, New Jersey and Illinois allow their governments to impose this unconstitutional nonsense on them. When you bring a firearm to my classes, my only concern is that it is unloaded and in a case or holster when you bring it into the classroom. I'll also check it to be sure it's safe to fire.
...selecting a gun for concealed carry?
The choices here are many and varied. I generally recommend a small-frame 5-shot revolver since these are easy to conceal and quite suitable for self-defense. However they are not always easy to shoot well. As you look at potential concealed carry handguns remember that 'small and light' is easiest to conceal and carry, but 'big and heavy' is easier to shoot and practice with. You're search is for the gun between those two that you can both carry and shoot well.
...what kind of practice is most useful?
You'll develop and maintain shooting skills best not by shooting a lot one time, but by shooting regularly and often. I recommend short frequent shooting sessions (e.g. firing 18-35 rounds from your pistol once a week for three months to develop proficiency, and then firing a few magazines or cylinders-full once a month to maintain your skill level.) Use big targets close enough to identify all of your bullet strikes so you will know how you are doing and can work on shot placement. Practice skills you're weak in first (e.g. firing in double-action instead of single-action.) And remember, accuracy first -- then speed.
