Alk, Real-life personal experience: My experience with small rifle primers in pistol cases, 9MM, 38 Super, 9X23 Winchester, mirrors yours. Never had a misfire or other issue in any semi-auto pistol, revolver or carbine using SRPs. I used SRPs to better resist flowing, cratering,etc. in high pressure loads. Sometimes chronographed velocities were a few FPS higher or lower, sometimes velocity spreads greater or less than small pistol primers,etc. But that's it.
