AzShooter Posted March 24 Share Posted March 24 I'm thinking of replacing my mainspring in my 617. It's got about 10 years with the same spring. I had to replace my firing pin this past weekend and had to change out my rebound spring for a heavier one. I'm thinking of just a stock mainspring from S&W. I've heard you can bend the mainspring for a lighter action but still shoot a variety of ammo. Any pictures of the properly bent spring would be helpful. Thanks in advance.

RePete Posted March 24 Share Posted March 24 (edited) I made a jif from a wood base and 2 1/8" needle bearings. This picture from Bang Inc should help. Edited March 24 by RePete Quote Link to comment Share on other sites More sharing options...

tator2k Posted May 5 Share Posted May 5 I typically use the Wolff main spring for all my revolvers. Instead of shimming the screw, I visited a local S&W gunsmith and picked up different length set screws to use. This way everything stays tight.

Toolguy Posted May 10 Share Posted May 10 I like the Wilson mainspring for stock actions. The original S&W one works best for the RevUp hammer. Quote Link to comment Share on other sites More sharing options...
AzShooter Posted May 10 Author Share Posted May 10 I appreciate that. Since I'm going to have the RevUp hammer kit I'll get a new stock mainspring. Quote Link to comment Share on other sites More sharing options...
Toolguy Posted May 13 Share Posted May 13 Hi Steven- We are currently in the middle of our annual May madhouse, getting ready for the Bianchi Cup. We had planned to have the KL hammers out before now, but having to tool up and make our own DA sears kind of threw a monkey wrench in that schedule. The Bianchi Cup is the last week in May. We are hoping to get the KL hammers out by the middle of June. We have not forgotten you or the other KL hammer people. There is only me and Tracy to do this, and we have been overloaded with many setbacks for most of a year. We are doing our best to git er done. We apologize for the long wait time. Best Regards- Warren and Tracy. Quote Link to comment Share on other sites More sharing options...

AzShooter Posted May 15 Author Share Posted May 15 I appreciate your response, Warren. I know what it's like to prepare for another venture. I can wait with no problems. Another month or two isn't something I can't live with. Thanks for letting me know. Steven Quote Link to comment Share on other sites More sharing options...
