Welcome aboard and a basic thought on a point that has been mentioned several times before. What is your mind set?
By this my question is more in line with the last six words provided by stormbringerr, "always be ready for the unexpected". You have made a choice and not only is this a choice - it is a life style choice as noted above.
You have a comfort zone you live in now and as you progress you no doubt will see how your comfort zone will change. You may start feeling comfortable with a handgun being close to you at home unloaded. Then at home loaded safety on. Loaded safety off with a round chambered as time progresses.
This forum as well as other fine forums have covered this issue of being ready. Ready for the unexpected, which is a choice and the more you prepare for the unexpected the way you see the world around you will change. I read once that many gunfights are over in 3 seconds. What can you do in 3 seconds? Not much more than draw and squeez the trigger.
Your mind set will change and you will look for many things that are not considered important at this moment. Your comfort with a handgun will increase and when you do not have it with you your mind will prompt you to be more cautious as a part of your normal group of tools is missing.
Your choices of where to go and what to do will change. Why - because you’re new comfort zone has changed and will result in your adaptation or modification of how you see the world around you.
Glad you are here and willing to be accountable for your own life and actions Mellman. Best wishes, stay safe and shoot straight.
