I shoot 45 super through my P220st regularly. Heavier spring made it pretty easy to do. It's a hard hitting round and will beat on the gun a bit. With a 24# spring my Springfield 1911 handled it fine and did well with it at the range last night.
I use +p ammo, but max is 23k vs 28k in super. 10mm is 37.5k so the frame should be ok? Might need a stronger spring?Hello
Can an out of box 45 handle the 45 super without modification? If mod needed what is required
Thank you
