There was a discussion in this forum that ended in November. Rather than resurrect it I'll ask here. Is the new tech ammo like ARX, Liberty Civil Defense, Underwood/LeHigh, etc. OK to use in my PM45? A lot of them are +P and I can shoot it in my Ruger P345. I'm not sure about my Kahr. What are the specs on +P in a PM/CM/CW45? Thx.
