230gr XTP, 7.2 gr Unique. 950 fps from my G21.
Those the #45160 Hornady's? I just picked up a bunch of these if so and I also have plenty of Unique on hand as well.
Yes.
They have a little more shazam than most 45ACP, but Quickload puts pressure around 21K PSI, so it's really only on the border of +P pressure.
In my G21 it runs fine with the factory spring, or with a Wolff 22-lb spring.
