If long or heavy trigger pull is an issue, then you need to consider going to a different format, like a true single-action-only, or double-action/single action. A good example of a true single-action-only pistol .380 that is very small is the Colt Mustang. There are some small 9mm's in sa only, but none nearly as small as the Colt Mustang. STI makes a very slim SA only, called the STI LS9.
