Before this thread gets locked....
Ther have been a few posters in this forum in the past claiming Medeco locks are unable to be bumped.
THIS IS NOT TRUE!
At the current ALOA convention in Charlotte NC, there have been classes where 3 versions of common Medeco cylinders have been bumped successfully and repeatedly.
The technique was video taped for training purposes.
Perhaps this will help to re-educate the Doubting Thomas'.
If and when an excerpt becomes available, hopefully someone will post the video (in the advanced forums)
