Yeah dude, I don't think you're going to get a premium price for a .380, even if it *is* a Glock. Not when I can pick up an LCP For sub-$200 all day erryday.
Not trying to be a *****. It's totally worth the price. It's just a hard sell for a weaker caliber when you can get a Shield 9mm for less than that, or a .380 for half that.
Good luck regardless, mah man. Someone out there will pick it up and be lucky to have it.
