On paper a 44 mag looks impressive, but folks forget those ballistics are from 8" barrels. Shoot those loads from shorter 3-4" barrels that people actually carry and things change.

The Glock chronographs 1315 fps with 200 gr hardcast lead. The 629 chronographs 1150 fps with 240 gr bullets. The 44 mag still has the edge, but not nearly as much as many think. Not enough for me to carry a longer, heavier gun that only holds about 1/3 the ammo.
I'm a Glock guy through and through, but what I do know is that 1315 fps with a 200gr in a G20 is HOT, no make that very hot. I've seen those numbers from 6" barrels, but not stock 4.6" barrels. Either way it's likely loaded well over pressure.

On the other hand, a 44 shooting a 240gr at 1150 from a 4" is generally a lower powered option. You could easily be shooting a 300gr hardcast that fast with the 4" bbl. So I'm inclined to ask, do you think the 44 and the 10mm are similar? I think the .44 is miles ahead of the 10mm and the 10mm much closer to the .40 S&W.
