I finally got my package from Freedom Fighter Tactical today. I ordered their 922(r) compliant trigger package, which includes the NP3 coated trigger, sear, and disconnector. I also ordered their 922(r) compliant follower. I now have 4 parts that are American-made, so I'm able to attach my collapsible stock and Benelli +2 magazine extension. I didn't go with a full-length tube because I plan on SBS'ing this little baby later this year, and don't wanna screw around with taking a heat gun to my $1700 shotgun.
Here's one crappy pic for now with everything installed; will try to get better ones of her all dirty after tomorrows range outing, as long as weather holds up.
I will say this- the trigger, sear and disconnector are so easy to install, its nuts. The trigger pull is now lighter, and the NP3 coated parts rock! You do need snap-ring pliers for the install though. Glad I picked some up earlier this week, as I knew the mag extension would require them for installation.
