+1, Wylde.
If you use the holster PROPERLY, there isn't a thing wrong with it! I was also quite annoyed when the story came out with an "instructor" that had an ND with one. He was a bonehead that wasn't using the equipment properly. SERPAs are very reliable IF properly maintained AND if you are properly trained in their use. They aren't "idiot-proof" and neither are Glocks.
Not to take this too far OT MSC...but did you use the military flap holster and if so, what's your opinion of it?
