I installed Ronno's trigger kit in my Winchester 1977, talk about a difference in trigger pull! The stock trigger makes the gun very difficult to take offhand shots. With Ron's kit, this should no longer be the case. I didn't do any other modifications to the trigger group, such as polishing. Unlike many trigger mods, this has full sear engagement, the safety works as it should, and a few hard smacks on the butt stock doesn't make the gun go off accidentally.
I haven't gotten a chance to shoot any groups or chronograph it yet. As I get more time to shoot, I'll provide some pictures and updates.
The installation is pretty straightforward, having a third hand would be nice, but is certainly optional
Kudos to Ron for developing this modification, it is far better, and in my opinion, much safer than most of the mods out there for this trigger group.
