I have seen several claims made that Glocks are unsafe due to the lack of an external safety. I have also read of two different motorcycle cops crashing and sliding on their holsters for several yards with no discharge. Does anyone have PERSONAL knowledge of a Glock firing accidentally? I carry a Glock 27 and I sometimes wonder if the family jewels are in harm's way. The piece was VERY accurate right out of the box, easy to conceal and very lightweight, so my safety is my only concern. I have a Taurus Millenium, also in .40 cal., a Uzi in 9mm and a S&W .357 revolver, but the Glock is the one I shoot best. I added Trijicon night sights, other than that no modifications. Your insights are appreciated.
