I carry a S&W 38 air weight for convenience, but in light of the many shootings, I'm upgrading to something with more rounds and more punch. I would rather be inconvenienced at this point than dead.
Normally a S&W 639. Often a CZ97B. The CZ weighs a little more but seems conceal better. Plus, the CZ is 10+1 of 45 ACP while the 639 is 9+1 of 9 mm. Both are double action,
