Sorry for the noob question, but what are combat sights and how do they differ from standard (?) sights? I find that I tend to always shoot a bit low. I was taught the "lolli-pop" method (what he called it) by my shooter instructor which was to keep the target sitting just on top of the front sight. The firearm I was using then is a Kel Tec PF-9, and now still use it and a P-32 (Thunder 380 coming soon).Bersa has combat sights, meaning front sight has to cover point of impact.
