I am trying to find a gunsmith either in OK or TX who I could have lighten trigger on my Freedom Arms Casull I have had for awhile. I travel enough that I thought it would be nice to drop of my 454 to a smith who was familiar with this single action. Its about a six pound let off, and I would like a slightly lighter pull for silhouette shooting. I live in southwest MO, and any smith I have spoken to on phone only work on semi-autos. Thanks for help.
