My primary carry gun is one of my gen3 Glock 23's. My preferred loads for this gun are the Federal 165gr HST and the Speer Gold Dot 165gr JHP "hot load" (#53970). It is currently loaded with the afore mentioned Gold Dot.
For 9mm, my choices are Federal 124gr +P HST and 147gr +P HTS, or Gold Dot 124gr +P JHP.
For .45ACP, I like the Federal 230gr +P HST or the Gold Dot 230gr +P JHP (this is a hot load).
