I would like to know how to bend a stock S&W revolver mainspring to get a lighter trigger pull. I know that I can just buy reduced power Wolf springs and have bought them in the past. But having put Wolf springs in a bunch of guns, I now have a bunch of stock mainsprings and I’d like to see what I can do with them.

A gunsmith once did this for me and the result was pretty good, not quite as smooth or light as a Wolf, but noticeably better than before. Also, this bent spring gave me a trigger pull that was a bit heavier than a Wolf spring and worked with primers that were too hard for that particular gun using a Wolf reduced power mainspring.

I got a nylon wedge from Brownells (that they advertise for this purpose) but I don't know how to use it.

Thanks for any advice you all can provide!
