If time from beep to lead on target was the only factor in choosing a CCW, then the Colt Navy would be my choice. Only handgun I’ve ever been able to draw and put lead on target in less than one second. Most guns I have to look for the front sight. With the Navy it’s just there automatically. For me it is the most naturally pointing handgun ever made. And a .375 caliber roundball at pert near 1000fps ain’t nothing to sneeze at.
