I worked over my Uberti shortly after opening the box. The lever spring required a near death grip. My action job consisted mainly of reducing the lever safety spring trigger spring & mainspring, plus finishing of the sear surfaces with an extra fine polishing stone. Mainspring was the toughest part - had to gring in a tiny little flat spot & groove at the "hook" - sping wanted to periodically pop out of place while using the rifle. It's been holding tight after that last mod - several years ago & lottsa shoosting 😆
