I always like to start a training session first with dry-firing and then move into accuracy drills/dot drills. Proper sight alignment and perfect trigger control are critical to achieving consistent accuracy on target.
I continue to train with my new Sig P365XL and am quite impressed with it. Two 5 shot groups at 3, 7, and 15 yards. I can tighten things up at 15, but not bad for a micro compact pistol.
