Hi Jimmy..... You don't provide much information here so, I'll assume you are using 1911 full frame, this is what my video deals with, you are using standard factory loads and the spring you have now isn't working for you anymore. Go to the Wolff website and follow their recommendation for the caliber you are using. If you are reloading, still start there and go up of down a little to dial in your best performance. Remember, these spring fatigue over time with use so, you should replace as needed. ...Don
