Good that you have a range where you can try them before you buy. I think you're onto the right track. Try the Sig p238 next, but also keep in mind the other guns LCP and Bodyguard were range guns. I've never head of such a problem with the LCP magazines on the forum here. It had to be a magazine plate that slipped off somehow. New magazine or whatever and that's fixed. She liked it. Give it another try. It's almost half the price of the Kahr P380. Don't get me wrong. I have two Kahr's and like them (cw9 and pm9), but that's a high price for .380 pocket gun. The bodyguard, I don't know enough about them, but the laser being out is because, .... well... it's a range gun and "everybody" uses the laser because it's there. Burned out the battery.
I have a feeling she would be happy with an LCP if she really liked the one she shot.
I have one. My wife likes it. Great little gun. Probably will never get rid of it, just because of what it is. Reliable, inexpensive, light, small, and easy to stick in the pocket.
