I load for a MP Shield 9mm and pack it when I'm not bear hunting or not in griz territory (G40 10mm in Griz country with 200g hardcast and XTPs doing nearly 1400 fps). I found that it appeared that generally, of the heavier 9mm bullets weights, the approx. 124g bullets seemed to produce the most energy. Manuals showed time and again, more energy with 124s than the heavier bullets. That being said, the loads I ended up with 120g hardcast at just under 1300fps and 124g XTPs at same--pretty potent little loads. I like to stagger the two bullets in the mag--never quite sure what your up against and bullets are designed for different purposes. That being said, this year after shooting a buck back in the wilderness and leaving 20lbs of long range gear at the ridge shot from, I was heading down into and across the basin to recover the buck, ran across a larger pile of bear scat and that little Shield 9mm looked pretty small. But folks that are doing the research are saying that 9mm is penetrating better (due to higher fps) than .40 and .45 and they'd pick it over those, but would prefer 10mm of all of them. But, I think you know all that, Ryan.
Edit: load above is 7.2g Longshot under the 120 and 124 bullets with Win small pistol primer--work up to that! It's a hot load--use at your own risk!
