How to reduce weight on a Beretta 92x performance?

Hi everyone, I'm a new member to this group and I need to find people who really understand how to use and modify a gun.

I bought a Beretta 92x performance 1 year ago and it was my first pistol, my idea was to compete in Steel challenge, PPC1500, IPSC and IDPA. The IPSC is a choice that I no longer consider because for me it would be too expensive and I would have neither the time nor the desire to produce shots and train. The PPC1500 is a competition that I do only to have fun with a group of friends since we don't have the place to train and all the competitions are abroad and it becomes difficult for us to always be present. MY PROBLEM is being able to compete in IDPA competitions which, however, have weight thresholds to respect and I, having NOT purchased the DEFENSIVE model, do not fall into any category. The pistol weighs 1350g (with empty magazine) and the maximum weight threshold for competitions such as CARRY OPTIC or ESP is 1219g. What advice do you give me to be able to reach this threshold?
