If you want small and hard hitting, get a Kahr with +p rounds in it, and an 8 round mag. You can pick up the CW for 200 less than the PM. You then have a much lighter pistol for maybe 100 dollars more than a Mak, that will take +p rounds, should you care to carry them.
Times change, why settle for heavier gun with less power? I like the Mak, but not for an EDC.
Then the XDS is a hard one to dispute, it's still lighter and it's a 45, that is really the end all argument for why to have one. Forget the metal/plastic argument, it's the final outcome that counts. Bigger faster bullets, in lighter pistols, that are accurate enough, to stake your life on are what counts.
If you must have a 380, then Kahr again makes a lighter 380 as does Seacamp, Kel-tek, Ruger ,and everone else, and the new "Pico" by Beretta, which comes with a light or laser built in, and the ability to switch to a 32 caliber factory barrel and use the same mags. The Pico has the makings of the next big thing , in it's modular, multi color, multi caliber, $300.00 priced, small pistol that I predict everyone will want, "for their wives", "caugh", or themselves to play with.
You will be able to customize the gun your way, and have a inexpensive 32 caliber plinker along with the 380. they should be doing this with the Nano also, soon, perhaps with a 40 frame next, and maybe a 45 next year.
But in reality why get a 380 when you can get a 9mm the same size?
