I am looking at buying a mainspring/rebound spring that includes a mainspring and three different rebound springs for my S&W 686 4".
The two I am deciding between are:
Wolff Shooter's Spring Pack or
Custom-TuneŽ Spring Kit | S&W K/L/N Frame Revolvers-Wilson Combat
What are your thoughts on either of these upgrade kits for those that have used them and is there another brand you would recommend more? Thanks!
