Don't bend springs, or cut coils from trigger rebound springs all that is bad bad bad
If you must, and have to have a lighter spring(God knows why) pick a Wolf spring and install it, I have seen too many shooters turn there revolvers into junk real fast, improper bending will change smooth action into ****. Also add unnecessary stress to adjoining parts, remember the trigger pull is a long cycle all the parts depend on one another for fit and proper spring tension,
The short answer install a Wolf Type II is reduced power, Type one is factory power. They have a bend in the proper area and the right temper.
