I noticed this a lot with the Taurus PT709 Slim. I would aim in one spot and the bullet would show up about 6" somewhere else. As I got closer to the target, the shots were closer to my aim, but it just seems (in my experience/opinion) that the smaller the gun, the more easy it is for the point of aim/point of impact to differ. I had a full size Ruger P95 and I would shoot that thing from around 30 yards and I could hit within an inch or two of the bulls-eye. When shooting the Taurus Slim (manufactured in 2013, brand new, cleaned and everything) from a similar distance, the hits on the target would be out of the target and to the side, sometimes near the bottom, right, left, etc. For me in situations like these it just takes practice and then you get more of a feeling for the gun and how to adjust to it, but still, with those two comparisons, what the heck?
