The argument that cops and those that anticipate being in a gunfight will be slowed down by an external manual safety and that is why Glocks don't have them makes no sense. If you really think that that external manual safety is going to slow you down and cost you your life, DON'T TURN IT ON IN THE FIRST PLACE. Every day at the local gun shop a half dozen women and almost as many men turn away from Glock handguns because of the lack of an external manual safety. No amount of explaining that "your finger is the safety" will make them reconsider a Glock. Glock, and gun shops that sell Glocks, are losing vast amounts of sales and profit by not offering external manual safeties.This is especially unfortunate because all of the internal safeties that a Glock DOES have that prevent accidental discharges from dropping the gun are EXACTLY what most novices need. Again, these women and men who turn away from Glocks are the ones who need those internal safeties the most.
