I would love to carry a larger piece but comfort and concealment are paramount to me for various reasons and my daily life. But the .380 ACP is my choice for EDC. Sometimes the LC-9 when do’able.
At 60, the other thing I have previously bashed as stupid, but now find immensely useful is a Laser sight.
I have a Viridian laser on my LCP, and the pocket holster has a magnet that deactivates the laser when holstered.
When you draw the pistol, the laser automatically comes on.
I can keep my focus (mentally, and in my bifocal age, optically) on the target without trying to tilt my head back to see the front sight.
Depends.
With me, it all depends on where I am going and what I am wearing (which is often dependent on the weather). As for where I carry on my person, most of the time it is an appendix carry. Thus, I am somewhat limited in what I carry in that position. Usually it is a snubbie .38 or a Glock 43, which is a 9 mm. In the winter, I can carry on my belt, so then it will be either a Glock 26 or a Glock 19.
I’m 68, so I am not going to carry anything more powerful or larger than that. Though, for home defense I keep a 6” .357 magnum handy; and I shoot that at the range on a regular basis.
