I am relatively new to Kahr arms but I shot a brand new one and the trigger did have a really gritty pull to it, after inspecting the frame I noticed that the trigger bar spring was not sliding smoothly along the trigger bar and was kind of catching on it causing the tough gritty pull, after about 50 shots the trigger smoothed out and the pull feels like it dropped by at least 2 lbs to the "Kahr trigger" we all know and love.
Could be that, otherwise I agree with berettabone and it sounds like the case is solved.
If she wants a pocket 380 I was handling some at the LGS today and the Remington RM380 had one of the easiest slides to rack I have ever seen on a pocket pistol, felt good in the hand too.
