Absolutely worth every penny, once this die is set it has a tolerance of 0.002 regardless of branding. I've had headspace issues with my G23, down to slight bumps and battery drain. Lee recommends a .840 trim length, but to preserve brass life I set mine to .845 and my problems are gone. This is a great product and my 223 sensor gave me the same results while waiting for my 9mm sensor to trim that too. Another fantastic five star Lee product for all day use.
