The reliability of Glock pistols is probably the reason most people who try them seem to become fanatical supporters of the gun. Most people will agree that reliability should be the #1 prerequisite for a defense gun. I had one gun that functioned similar to your .380 and I got rid of it, if you can't depend on it it's useless as far as I'm concerned. (It was a .32 Beretta Tomcat)
For carrying my G-26 a high ride 3 slot pancake holster is very comfortable and pretty easy to conceal.
