Last year I witnessed ATF remove a gun dealer from a show because he was selling some Packmayr holsters and wallet holsters.
Pachmayr confirned that the logic behind the rule is if the gun can still be fired from inside your pocket WITHOUT removing the gun from the wallet, holster or container. The Pachmayr holster still has the trigger exposed and the barrel is not blocked so a round can leave the gun hence violation.
So I guess Uncle Mikes inside the pocket holsters are illegal too? I could shoot if from inside a coat pocket with it still holstered. BUT, the barrel is blocked. Although it can still be shot through.
The ATF rules for pocket holsters say nothing about what Pachmayr is saying.............
