I have been reading threads on here for some time and something that almost never comes up is the glock safe-t-blok (I did a search too). I see one guy that stood up and said he uses one, why is this? Is there a reason why no one uses then or are they not talked about because they are not cool? Its just not here either, I looked it up on you-tube and there are only two videos that mention them. One guy said they are not holster friendly with a form fitted holster. I like some thoughts if they are worth the 15.00 or will it get throw in a draw and forgot about?
