I've been asked this question many times. The trigger needs the full length of travel to operate in DA. A very slight amount of excess trigger travel can be felt in DA but it is needed to reset for the next round. Unfortunately, that has a big influence on SA trigger travel. This is not unique just to Ruger P-guns. All DA/SA semi-autos tend to have a lot of trigger travel in SA. There's really nothing you can do about it but practice and get used to it.
