9mm 124 grain JHP factory load that will reliably hit 1,200 f/s out of 3.6-3.7" barre

Fired from a SIG P229 with a slutty 3.8" barrel . . .

That's interesting and useful. I was thinking this would be a 1150-1175 f/s round out of the barrel lengths I'm interested in.

Based on chrono work in recent years, the HST 124+P has been loaded quite warm... I've gotten a hair over 1200 from two different lots in a G43X (3.41"), and 1230-1240 from 4" Glocks.
