Just catching up with this thread and I figured I would throw my 2 cents in here.
I am a Tactical Firearms Instructor and hold several LE and MIL Instructor certs.
1st- The ONLY pistols that use a "CLIP" are revolvers using half-moon or full-moon "clips" to hold casings without a rim, such as 45 acp in a revolver. As far as rifles are concerned, the ONLY rifles that use "clips" are the M1 Garand style that uses an "en bloc clip".
All ammunition devices utilizing a Magazine body; follower; spring; and base-plate are "MAGAZINES"...not "clips"...sorry, but this is one of those things that we spend a ridiculous amount of time beating out of peoples vocabulary.
2nd- .380ACP is not what you want in a gun fight, energy sucks and reliability isn't far behind.
Just because lots of people have managed to die from a 22 long rifle, doesn't make it a good choice in a gun fight.
That having been said, I'll take the first loaded weapon that I can get my hands on, in a gunfight. However, if I am planning ahead and have a choice, it would be 45 ACP and then 40 S&W as carry options. I carry a full size 1911 and conceal it well with t-shirt and jeans. If I was always in shorts, I'd be carrying a compact in one of these calibers. I want to stop the threat...not tickle him to death.
3rd- Carry ammo should be the best you can buy. You are intending to save your butt with this gun and ammo combination, it is critically important that you get the most bang for your buck. Buy the best ammo you can and run a box or two through your intended carry gun. If you have malfunctions...try another brand of ammo or find a better gun.
Regarding ammo "carry life", I will pack the same rounds around until they start showing wear from being chambered a few times.
I do a fair amount of dry practice and range practice, so the carry ammo gets unloaded and loaded frequently. After that 25 rd box of carry ammo shows wear, it gets replaced and goes into the practice pile.
.380 that I have used and found reliable would be 1st-Remington Golden Sabers, 2nd-Winchester Silvertips.
So the morals of this story are:
Bring a real gun to a gunfight...Assuming you intend to win of course.
Use the best ammo you can find, that you have tested and found to be reliable.
It is a Magazine, or a Mag...like we tell the students on the range..."I'm willing to bet you don't have a single firearm that actually uses a CLIP."
