I will tell you this much, the ALS holster will be the only OWB holster Ill ever own again, and for many others I know as well. I just cant stand non-locking holsters any more, one time too many of my handgun getting thrown by my backpack strap, taking it off. The ALS is such a natural draw, disengaging the lock, it took no time going from a standard kydex holster to the ALS, and do difference in speed or efficiency in the draw. A secondary benefit is it wont wear down your finish no where near as fast as a kydex holster or other friction based holsters.
