The Raptor is the new level 4 holster? Me thinks we are getting ahead of ourselves, letting the equipment replace training. Make a holster so difficult to draw from then you have problems. I have seen them and came away unimpressed. There is nothing wrong with the current 070 holster at all, or the roll top model (6820?) with the sentry added to it.
Compound all the retentions with the fact officers have trouble drawing from a level 1 holster, it is asking for trouble.
Rant mode off.
The belt sounds like a good idea, save everyone's back.
