Delphi-

my 'challenge' to you:

don't buy any more firearms right now.

take what you have and find an IDPA, USPA or 3gun event near you and spend ..oh.. 6 months MINIMUM (At least 1x per month) learning the ropes (people there will be glad to show you (if you're willing to learn))

observe
listen
practice


I guarantee your outlook will change after all that.
