If, by some chance I was involved in another lethal force encounter, and if I were to get shot in my strong side arm/hand, it is likely that my handgun would eventually suffer a malfunction from shooting one-handed from my support side. There’s the possibility that my magazine could pop out, or that I would need to conduct a magazine exchange. If I have rounded or low profile sights, how will I rack my firearm? Maybe I could come up with some creative way to rack my gun, but from my experience, those ways are more likely to result in a malfunction as opposed to fixing one. Since I know that I may need the 90-degree angle that sights provide in order to rack my firearm on my holster, belt, shoe, or some other object with an edge, I make sure the surface of any sights I select allows me to do that without a problem.
