Glock 21 45 Super versus Glock 20 10mm - 07/27/16
Looking for a Glock pistol that can deliver 600-700 ft. lbs of energy.
Considering the Glock 21 in 45 ACP OR Glock 20 10mm.
On either pistol an aftermarket barrel with more case head support will be installed.
On the surface, it seems that the G21 45 ACP with aftermarket barrel could deliver equal power to the 10mm with the advantage of the ablity to use cheaper, more widely available ammo.
Besides the cost of a heavier recoil spring needed for the 45 is there a downside?
