Scooter summed it up. Buy some Wolf springs. Work on hammer return springs to lighten trigger pull, you should get three in a kit. Lightening the hammer reduces pull but also increases time to ignition. Bad for light strikes and accuracy. I always work with stones and lube on the hammer return mechanism and use an Aftermarket spring with strain screw completely tight for the hammer in K frames and J frames I do not alter the coil spring.
