Specifically the .357 magnum 125gr JHP has the best one shot stop record, primarily because most cops were issued that round for a number of years. MANY years in fact. Given enough time, any round would collect impressive results. The problem with this load is that it has serious recoil, and dramatic muzzle flash which tends to impede the follow up shot, especially at night.

Caliber and bullet weight aren't as important today as bullet configuration. Hydra-Shok was the first of the high speed/low drag wonder-rounds. Next came the infamous Black Talon and the now defunct nyclad which insured good expansion from snub nosed .38 sp standard pressure loads.

Then came the prefrangible Glaser and MagSafe loads which have been phenomenal in warm weather but tend to break up too early when the cold brings heavy jackets.

For the 45ACP, Speer has had a great load. The JHP nose is so wide and gaping it has been dubbed "The Flying Ashtray." But it has had feeding problems in some guns. Hydra Shok is building an impressive record for the 45.

The Speer GoldDot in 45ACP will stop hard if there is a vertical area before the feed ramp starts. The Colt Officers barrels are built that way. Glock feed ramps are smooth all the way, but often don't completely support the casehead. The brass can balloon and make reloading impossible.

I have always had good results with Federal HydraShok cartridges, for over a decade, in terms of feeding. They will flow through my Sig .380, my friend's Colt, any 9mm, and have never jammed over a history of less than fifty rounds in my mil-spec 1911. The shape is similar to FMJ rounds (ball), and factory ramps seem to accept them.

But I'm still using Silvertips in my .357.
