So i started shooting only 7 months ago. My first guns (bought them just a week apart) were a .45 semi auto and a 2 inch barrel .357, the Taurus 617. At first i was way better with the revolver. Then, when i got my carry permit started carrying more and more, hence practicing more and more with a compact .40 semi auto, to a point that i stoped taking the revolver to the range. So when i decided to finally take it out of the box and shoot it i foud out that i need to aim like an inch lower than where i want to hit. This does not happen with my other revolvers including another .357 with a 6 inch barrel and a .38 with also a 2 inch barrel. So i wonder if im doing something wrong or it is normal with the 617 model(BTW it has fixed sights). Any advice woud be greatly appreciated!
