I looked thru all the Q & As and found several threads about the 67 E, but no reference to my problem. When I fire the gun, and try to eject the hull, the slide will not move until I press the release. It doesn't do this all the time, just sometimes. I have not took the gun apart to look at it yet. Thought I might get some info on what to look for when I take it down. Any help would be greatly appreciated. From what I can find about the gun, it is one of the later models. It has the choke tubes and the vented rib. The serial number is 3790xxxDN. Can anyone date it for me? Thanks for any info sent!

Oh, this is NOT when there are no shells left in the magazine. This is when the magazine has shells in it to be loaded that the slide won't move without pressing the release.

Sorry, wrong section. Please delete if this is the wrong section. I'm confused.
