This version of the GO Pistol Plug Spinner has been supplemented by the SSE Plug Spinner Adapter for bump keys:
If you turn the cylinder core with a bump key and pull back the bolt in the lock, you may need to be able to turn it further to pull back the latch and so open the door from the outside. To avoid having to turn the cylinder core again by bumping it, use the innovative
SSE Plug Spinner Adapter for bump keys.
