I have seen testing for the critical duty 135+p from 3.0-3.5 inch guns and it does well across tests in those barrel lengths. Expansion is limited, and it may be that the new GD2 +p is better, but the CD performance was certainly acceptable and that’s an easily found load. It also “feels” like a standard pressure, recoil wise, to me. I have found function very good in a 43x and P365 with no failures in 4-500 rounds across those platforms.
