The above poster is correct if your shooting well with the 19 and dropping your groups you need to excersice your hands and build up your intrinsic muscles. These small muscles is what gives your hands and fingers strength. Don't even think about a 380. If grip comfort is a issue see if you can fondle a walther p99 you might like the grip more but until you start doing hand excersises your going to have a problem.
