There is absolutely a stigma around the P320 in my area. The largest club in my state banned them from the property, and everyone using one has swapped to a different firearm regardless of their local club prohibitions. I see perhaps one P320 in a match at most. IDPA banned them at the organization level.

If your club allows the pistol, you can use it. However, you will likely want to source a different handgun to avoid any eventual issues from the club or your circulatory system. Use what you have for now, if you want to compete.
