I know these rounds are not the most effective and are less than ideal, but in some cases some people can only use weapons of these smaller calibers or simply choose to.
I can not be the only person to wonder.....
For .38 Spl, use Gold Dots, which is the only modern (4th Gen) bullet available in revolver calibers. It performs quite well.
For .380 and smaller calibers, none of the hollowpoint designs will give sufficient penetration; they simply don't have enough mass and speed to both expand and penetrate. Typically, you only get about 7-8" max from the best .380 JHP loads. The smaller calibers are worse. So, if you must carry those smaller calibers, FMJ ammo is recommended, because at least it will penetrate enough to reach the vitals reliably.
But you can see why folks in the know recommend against using calibers smaller than 9mm for defensive/CCW use.
