Is the Precision1 .380 effectively loaded "hot" to account for the incredible boost in both penetration and expansion? If so, it may not be the best long-term load for a micropistol.
Unlike the 9mm, the 380 is a low pressure load with the maximum pressure at 21,000 psi vs 35,000 psi for a 9mm and 38,500 psi for the 9mm +P.
Modern firearms should have no problems with the hot 380's.
You get up into the big boys like the 454 and 460 S&W and they are rated at 65,000 psi.
