For those of you who own a 920 or 912. I noticed the bolt will only lock open if the trigger has been squeezed. This seems it will be a nuisance, if I have a shell in the chamber and need to clear the weapon prior to changing stations I have to open the bolt and hold it open with one hand, pull out the shell, release the bolt, dry fire, then pull the bolt back so it will lock in place. Does anyone else have the same problem or is a standard "feature" of a CZ semi-auto?
