Wife has a CW 9 and CW 380. Both are very accurate and reliable after break in. Kahr recommends 200 rounds for break in but neither gun failed after 20 rounds. People criticize this about Kahr pistols but I believe it contributes to accuracy. They are built with tight tolarences and require breaking in.
My wife has put enough rounds through her two that she is very comfortable carrying either one for personal protection. The only choice is based on what she is wearing that day.
That's after carrying a sig 238, Ruger LCP, Walter PPK, and a Taurus TCP.
Oddly enough she also likes her bersa Thunder 380. It never leaves her truck. It's almost identical to the PPK but she likes the bersa better. It's just too heavy for her to use as a carry gun.
Not suggesting this is a woman's gun. I've tried to talk her out of her CW380. She said "buy your own".
