Instead of an outright ban, I have a solution. There are many military units that have been issued/chosen/been told they are using this absurdly dangerous holster. For you guys here is what I've got-
With the holster empty take a long sharp knife, reach down inside the SERPA and cut/saw the plastic piece that rests inside the trigger guard when the weapon is holstered. You may need to use a set of needle nose pliers to help rip that nub off. This will make the push button a non issue and the tension screw can be used for retention.
Whoever chose this piece of shit to be issued to anyone- you're an inexperienced pistol shooter who has no common sense. Hope you got a decent kickback from Blackhawk.
