Hi, Herbert!
Been a while since we've "talked". You helped early on with other issues!
The action does jam, with two or more in the mag. But, with one round it slides through smooth as everything, but, if I do the "brisk" in operating the lever, it falls out of the action, just dangling there on the lever screw.
I assume that the gap is between the end of the trigger guard and the block groove?
My son-in-law has a spencer too. His does not have the "fall out of the action" issues that mine does. We compared them and measured the gaps (been looking for the numbers, measured with a feeler gauge). That said, my gap is half what his is ... is there some else?
Again, thanks for your help and interest!
David
