Welcome to Glock Talk.
"Current best," of course is amatter of opinion, but the GATE section is about opinions, so...
In .45 ACP, I generally run a high-tech hollow point at standard velocity. Once feeding reliability has been established, yhou have the same recoil and trajectory as less expensive practice 230 grain hardball. The better 230 grain JHP loads have established an excellent track record in the field in terms of doing what they're designed to do.
In .38 Special, I generally go with Speer 135 grain +P Gold Dot in my snubbies (what it was designed for) and 158 grain Remington Express lead semi-wadcutter +P hollow point for my four-inch .38s.
9mm is the biggest bone of contention in the "caliber wars." Personally, everything I've been able to research leads me to Winchester 127 grain Ranger-T +P+ and Speer Gold Dot 124 grain +P, followed by any of several good 115 grain jacketed hollow point rounds in the 1300 foot-second velocity range.
