Assuming you didn't meet in a CCW class or on the range how do you bring up the subject to gauge the others feelings on the subject before the pants hit the floor so to speak or even from a random hug/touch where you don't want someone freaking out in public.
One of the last girls I dated was while I was taking my NRA class and I would mention I was going to range etc... and she was cool with it. I even asked at one point if she was uneasy about myself carrying and she said no it was cool and it actually made her think about getting something to protect her and her daughter in their home. Unfortunately we had to stop dating because her daughter was having some issue and she needed to concentrate on that.
Then I dated a police officer a few times and mentioned my looking into wanting to apply for the volunteer force and I was getting my permit. Didn't seem to phase her in the least and she only commented on the long process and that one of her friends was also getting hers and though it was a good idea for home defense at the very least.
But assuming you already have your CCW and carry how do you gently bring up the subject?
