    For Christmas I bought my wife a Taurus model 651 5-shot revolver in .357. (This model is very similar to the Taurus model 605, and most internal parts are interchangeable between the two models.) The gun is very nice, but she said the trigger force was too high.

    So I looked into installing some lighter springs. W.C. Wolff Co. sells the following replacement springs for the 605/651 revolvers:

    Hammer Spring (Mainspring)
    Reduced Power: 9 Lb. (factory is 11 lbs.)

    Trigger Return Spring
    Reduced Power: 6.5 (factory is 14 lbs.)

    Trigger Return Spring
    Reduced Power: 9 Lb. (factory is 14 lbs.)

    I purchased a kit from Wolff that contains all three springs. After disassembling the gun I did the following:

    1. I removed the 11 lb. factory hammer spring and installed the 9 lb. Wolff hammer spring.

    2. I removed the 14 lb. factory trigger return spring and installed the 6.5 lb. Wolff trigger return spring.

    After reassembling the gun, I test fired it in the backyard using Federal .38 FMJ. About 20% of the time the round "hangfired," which means the firing pin hit the primer but the round did not go off.

    There's no doubt that the problem is due to the lighter springs. So what should I do? Should I remove the 6.5 lb. Wolff trigger return spring and install the 9 lb. Wolff trigger return spring? Should I remove the 9 lb. Wolff hammer spring and install the 11 lb. factory hammer spring? Or should I reinstall the both factory springs?

    Thank you

    If the trigger is resetting okay with the lighter spring, I'd just reinstall the factory mainspring.

    Good Luck...

    Taurus Model 970 take-down?

    I have a model 970 that I would like to take-down and smooth up the action. No complaints, just like a smoothing on all new revolvers. Is there anything that will go sproing and and bounce around my catch-the-parts bag? Any information will be appreciated.

    You can reduce the power of the factory spring by using a bench grinder and a rod that fits through the inner diameter of the spring. The rod should have a close fit but not snug. The spring needs to spin on the rod when it is being ground on the bench grinder. Spin the spring on the bench grinder uniformly and only take off enough material so that a flat is made on the round spring. It is always a good idea to have a back up replacement spring in case you take too much off. With a little patience you should be able to tackle it with no problems. Just remove some, reinstall and check. Of course you need to test fire it when you are done. A quick check can be done by inserting a unsharpened pencil through the bore and contact the firing pin hole. This will tell you how hard the firing pin is hitting. It's also fun to shoot pencils across the room. For more fun insert the eraser end up against the firing pin hole.
