I ran across this on another forum .
Now i think its an elegant innovative solution to using a glock in some applications such as pocket carry , or for duty use where a weapon may be snatched/taken away . I am not saying everyone needs or wants one on thier glock but for many that have wanted the option of a manual safety on a glock this looks like a fairly cheap easy way to get one .
Apparently top glock is selling them for about $60.00 or so
