Don't go .380,,, go 9mm or .38 Special/.357 mag
I really don't have anything against the .380 cartridge except lately (more than a year) it's been the most expensive medium caliber cartridge out there.
I agree with everyone who is recommending a 4" .38,,,
It's hard to beat a S&W Model 10 or a Ruger single six or service six.
If you found a good deal, don't shy away from a .357 magnum,,,
.38 Special ammo fits and shoots out of them as well.
Honestly though, your best bet is just to pick them up and see how they feel in your hand.
