I try to practice and in the relatively benign atmosphere of a range am generally accurate. However I do not believe I would perform nearly as well in a defensive situation where lives literally were at issue. According to my reading of those famous FBI reports, most shots fired in combat are complete misses (i.e. "over-shoots" rather than over-penetrations ) Lights, lasers are all good. But would it also be useful to use tracer ammunition to try and minimize common over-shooting?
Or are there good reasons for not using tracers?
Sorry if this is a foolish New-Be question that has already been covered. I didn't find it doing a search.
