The last few days, I have been shooting a tilted eight inch steel at 50 yards, which effectively makes the target even smaller. After experimenting with various techniques, I have found that across multiple platforms (Glock 19, B92, P239, my best hit rate is to pin the trigger after the shot, let the the gun and sights settle in recoil, flip off the face of the trigger, and roll through in one continuous motion. Initially, this seemed counter intuitive, as it would seem to be less "stabilized" than resetting the trigger in recoil, and then working through just the remaining travel from the wall to break in one motion.
Discussing this with YVK, he mentioned Ernest Langdon advocates a similar technique for difficult shots. Also same advice from some super face shooter guy he trained with.
What are others doing in this regard with very difficult shots?
PS: the little 239 is a shooting machine for a relatively small pistol.
