That's correct. This is because the valve knocker has a secondary feature designed in to it to allow it to swing UP in the event it is extended forward when a magazine is inserted. The extended flow valve in the magazine magazine will push the extension *UP* and out of the way.
Following that, the first time the slide is racked back, it will consequently lock the hammer back as well as trip the disconnect lever, which allows the valve knocker to be pulled backwards in to its natural resting state.
Once pulled back, the valve knocker is now clear of the extended flow valve and will drop down in to it's normal position and primed to strike directly forward against the flow valve. Once the trigger is pulled, the sear clears the hammer, which allows it to strike forward against the valve knocker which strikes directly forward in to the flow valve to create the shot.
You need to create a method that will internally release the connection between the hammer and the valve knocker if you want the gas flow to be disconnected. If you're not using the slide as the timing mechanism, you'll need to figure out another way to do it, which is why I think this would be anywhere near an easy project.
