CR Speed WSMII Holster-Mods or Fixes??

[SM1986]

New to Me STI edge and CR Speed WSMII rig...have used it in a few matches without issue. everything appears to be adjusted set up correctly...but...shot a match today and had my gun fall out of the holster while taping/ pasting. Didnt hit or bump anything. Came close a second time after very lightly bumping lightly into a chair. 

 

Reading more about this rig it seems that its designed to have a designed in "drawn through lock " ability, but are these holsters supposed to be that sensitive to being bumped. Is there a common wear item, mod, or adjustment to make this less of an issue? Doesnt appear to be a tension adjustment other that the tg fit shims. 

 

Any help appreciated.

not heard of this happening if the gun's locked in properly, once saw a guy pull his whole rig off his velcro belt while trying to draw with the lock on.

Either the holster is not set up properly or there is a faulty part on the WSM holster.  I have used CR holsters off and on since the early 1990's and have never seen such a problem possibe. I have never had it happen unlocked let alone locked.

Check to make sure you don’t have excess play on the muzzle end. It should be set to where the muzzle cup is up tight to the barrel and the lock lever just slides on. Have been using a cr speed for a very long time and never has a gun fall out when locked.

Thanks to all for the replies.Good to know this isnt just something I'm stuck with. I ordered a maitenence kit, which should be from the loooks if it a whole rebuild; from CR speed and will be going through the whole thing.
