Handgun Development for Self-Defense

I'm looking to develop a semi-automatic handgun primarily for self-defense purposes. I have a general idea of how I want it to work, but I need a skilled firearm engineer to help conceptualize the necessary components to make the product functional. Ideal Skills: - Expertise in firearm engineering - Experience in handgun design - Knowledge of self-defense weaponry - Familiarity with semi-automatic action types Responsibilities: - Design a functional semi-automatic handgun - Consider the necessary components for self-defense use - Help bring my general ideas to life
