Never messed with the super, but it interests me.
But, 5" steel frames are all that's recommended for super use.
Longer would be acceptable, probably.
You are putting more stress on the gun than the design was ment for.
It will handle it, properly set up.
But the alloy frame is weaker, and a shorter barrel shortens the cycle, and removes
mass.
So more stress, less ability to handle it.
