Unfortunately I have reached the age where so many devices and gadgets have names that are beyond my recollection!! I have two options for Glocks - one is the soft rubber plug which Muss Muggins was kind enough to decipher. The other is the Saf-T-Blok (hereafter called 'STB'). The STB is fairly well engineered and can be flicked out in less than a second. The plug takes longer to push out and doesn't block the trigger as effectively. I'm big on pitchers - I can post a photo of the plug (and more info) if someone is interested. The STB is fairly well known and run about $12 on Amazon...

I recognize that any comments about plugs and STB's is pouring salt into the wounds of those who think they are an abomination. Again, I want to point out that I have the very good fortune to have a working wife, and thus we are able to live in a safe area. But, I have to go out before sunrise (for now) on weekday mornings so either the 442, or 360J or 640 will be going along for the ride.
