Q-lock and egg
Your egg should not fall out of your q-lock.
Mine doesn't. Can't see how it can if it on tight enough.
My method. With q-lock lever open, tighten up q-lock so that the feedneck is a bit stiff to get in. After it in tighten up a bit more, then close the lever. Make sure during the day you give the q-lock another tighten every now and again to make sure all secure.
