Something (a ultra concealed .22) is better than nothing (a cell phone), as I suspect the people that were murdered in Orlando when hiding in the bathroom stalls would agree with (and the people in France hiding under tables/behind counters as well). I, for the life of me, cannot believe that if you are truly concerned about CCWing and defending your right to life, that you wouldn't want the most effective tool and be trained in how to use it. With modern pistol design, cartridge design, holster design, and "fashion", there is ZERO argument that a person can't effectively conceal and deploy, at the minimum, a single stack 8 round 9mm at 25 yards. Most people, who WANT TO make the choice to, can carry a double stack, semi-auto, and comfortably conceal it.
One of my friends is currently embarking down the CCW road, and he asks me all of the time about "how do you do that?" (small groups, consistent patterns, conceal/draw/reload, etc.) and I have to keep telling him that I train, practice, and compete regularly and have for the past 20 years. He's only been doing that for two (hey, at least he realized the importance of it, if only 20 years late), but he isn't giving up. It's important enough for him to take classes, join a range, try various pistols, holsters, gear, etc. to find what works for him.
There are plenty of options available to carry an accurate semi-auto comfortably, with spare ammo that is equally as concealable and carryable. This is definitely comfortable AND comforting to me ...
