The stock commander size springs fit the tac.The spring you Got from Don was cut down by him.If you buy pre-cut springs from Don,old school or james you will be fine but if you would like to try some soft spring you will have to do some cutting 8)
My mistake. When I got mine, Don was not providing the springs and we were getting those from Wolff. We were ordering the recoil springs for the Springfield Compact with 4" barrel and they fit just fine with no cutting. I should have checked my Wolff invoice before posting. Can't remember anything anymore. Old age sucks.
