Pretty bogus statements,260.
Both the 320 and the m69 are single lugged guns with about the same reciever diameter.
The m320 trigger group is nothing fancy certainly no better than a 880 series Marlin.
A model 320 man sized?
You crack me up..
Regarding the triggers, the 880 series Marlins are quite a bit more recent than the 310/320 and you clearly stated "of the era".
We seem to disagree on a lot of things, but that is to be expected from different people with their different perspectives and degrees of experience.
