I bought the external trigger safety for my G19. It is primarily my nightstand gun so I leave it in condition 1 with my 136 lumen light attached to the rail. A quick nudge of the trigger finger and the gun is hot and ready. I like the little trigger piece because I don't have to worry about where and how fast I have to grab the gun if needed. That said, would it kill Glock to make a model of their great gun with a thumb safety? It's not like Glock is an icon or anything. And if they did, you wouldn't see any more pansey whiners talking about Glock leg because they would be carrying the new California-ized, dumbed down gun. I just picked up an LC9 and you want to talk about safety overkill!!!! Must have been designed in the land of fruits and nuts.
