Training is more important than equipment. Gunsite, Lethal Force Institute, Thunder Ranch, and Storm Mountain are excellent schools, and are worth every penny (even if it is a lot of pennies). If you’re new to the subject and are having problems with your equipment, it’s probably not the equipment. Hitting the target fast, accurate, and hard is more important than what you’re hitting it with. Complex equipment configurations will give you more problems than simple configurations, at least until you’re so good that you are finally better than the equipment (few are). When you know the basics well, you can do well enough with anything.
You can’t miss fast enough to hit.
Only hits count.
Safety rules aside, shooting comes down to just three words:
Front sight, press.
When you understand what that means, and can do it every time, you are ready.
