There is also the size difference, and actual performance vs published ballistics. This is my G-20 next to my 3" barreled 629. The Glock is over 3/4 lb lighter and still 1" shorter.
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.
