Where do you live? Someone may be in your area, that would show you some things.
#1 BE SAFE, practice safe gun handling procedures ALWAYS.
For beginning dryfire practice, find some reading/video on proper stance, grip technique, and draw. Some things I found useful when I started were the "Pro-tips" from shooting usa's website. Real pros giving basic information on the fundamentals.
Get a holster, put a target on the wall (safe direction) triple check unloaded, no ammo in room/area, focus on target, draw, aim (change focus to front sight only) and press until "click". Repeat, as smoothly as possible for at least 1,000 draws. Then start other things, like transitions to the next target, or relaods.
Master the fundamentals, everything else is based on that!!!
