OK - first off, I've never been inside a Smith revolver before (40 years of 1911s, but that's another story

I watched the YouTube movie thingie - but that is for a coiled main - and mine has a leaf spring. My logic says I need to take out the tension screw at the bottom of the grip to remove the main - correct? If so - that sombitch is in there TIGHT. Before I go postal on it - I want to make sure that that is, in fact, the best way to get the mainspring out.

TIA revolver pistoleros

PS - any YouTube videos of N frame/leaf spring take down????
