I found this and was thinking of doing the same with my simpson. I am the guy who has a second unloader on my simpson 420, against forum advice, and no catastrophes yet. I have run it this way for 2 years and it has allowed me to not be on the trigger all the time but it is not advised to do this, but I was cheap when I started out and just haven’t switched it yet. But again, it is not advised to run a second unloader that cost $85, just saying.
