Got the 1900 put on my PP and brought it home today...I lucked out...The mainspring is OK...
When I took the grips off and turned it over, I could see the toggle link flopping back & forth...Not sure how that got loose...The claw on the mainspring wasn't catching it...I poked it a couple times, and it engaged, and now there's no "slop"...
...Just 111 years worth of crud...
Is the mainspring supposed to fit in a slot at the bottom of the gripframe???
