You said to get back to you about getting your head banged into the concrete..Never have,so tell me about it.
First-If your getting your head bashed in,the guy doesn't have a weapon...
Second-How many times have you been in that very scenario needing a bullet in the chamber of a semi-auto while getting your head bashed in,as you posted?
Third-If you have just a few seconds while an "armed" person threatens your life...How much difference in seconds or milli-seconds does it take to run the slide versus pull the hammer back or even click the safety off.
