Ya, If the gun can be drawn locked, it can fall out locked. Got the CR speed of a prize table and it was gone within a week and I stayed with the Kydex till I got my STI open gun and went with the Racemaster. Use the same holster for the limited and open STI as well as the backup glock open gun. With the lock on it is not coming out at all and the lock is very fast to kick off. For stand and draw its not needed but with the weird laying down, seated in a crappy chair etc starts the gun is rock solid
