Can the average guy install a Wolff spring kit ( mainspring and rebound springs) in a 629 44 mag, or is this something for a gunsmith only? This sounds crazy, but I had an expensive action job done on this pistol a couple years back, and now it will only shoot with federal primers. But I want 100% reliable firing with any type of reloads or factory ammo I decide to feed it. I wanted a better trigger pull, but in hindsight, for a hunting pistol I wish I had left it as is from the factory. I was thinking about removing the springs that were installed and replacing them with the spring pack for $18.29 from Midway. I was hoping this would be a do-it-yourself job. Who out there can tell me if this is an easy job or big job?
