I still wish Glock would put manual thumb safety devices on their firearms. You can go blue in the mouth giving me all the safe action reasons why I don't need one, but you all fail to realize one thing. 

Stupidity happens. Just like shit does.

You made manual thumb safety available for military trials. So you are capable of making them. Just offer it to the public and watch your sales increase exponentially overnight. 

I won't own a gun without a manual thumb safety. So until Glock makes one available. I'll never own a Glock. Which kinda sucks.
