Actually that is common for Revolvers(or scissors) period.To make the scissor work means both parts(the pivot point) converge at a point much further forward than the line of a conventional shackle(does that make sense).If you look close you can see where the bolt hits(it got worse from there).
that's werid, on my old warn out springs the shackle hit the back, that be why i did put new springs in ???? humm well have to see were this goes... thanks
