NJ shooter confirmed it.... the 410519BK-R does indeed cover the muzzle end on the 5" models.
The other fellow who stated his holster fits the millenium with front sight covered but not the the OSS obviously has the 410529BK-R which obviously wouldn't cover the front end on the LS either because they are both 5"... if it covers the front on the standard which is 4" then it kinda stands to reason it would hide the front on the millenium because it's even shorter yet. That was sort of a "duh" factor.
@K4SWB... you inquired about the 410529BK-R again, which they and we already have concluded many times over is only as long as the 4" standard 24/7. It's the 410519BK-R that will cover the 5" as NJ shooter just confirmed. There's no confusion now.
***please take note: the difference in part numbers is 4105(ONE)9BK-R and 4105(TWO)9BK-R I don't know if maybe you were missing that or what. ?? maybe
