Keeping An Open Mind
There is a possibility that there may be someone in this forum that just found out that the world they live in is different now than yesterday. A first time handgun buyer, a lady who was approached in the parking lot, or someone who was robbed at gun point.
Could be they joined this forum because they had no idea who could advise them without ridicule.
Everyone has an opionion on what to carry, specific ammunition choices, and who will give the best training.
I am the first one to say keep an open mind! Yes, there probably isn't much new under the "tactical" sun. There could be some one here that this is hearing this for the first time.
You can't learn too much, listen to the folks that are willing to teach. Take what YOU need, filter out the fluff,and maybe you will learn something "new".
