....with magwell it's not legal for USPSA Production.
High capacity mags can be loaded to ten rounds and magwell removed and should be OK for Productiion or Carry Optics....as long as it fits in the USPSA box with magazine inserted.
But....I believe, the specs of the gun must be submitted to USPSA and then it must be added to the approved gun list.
Any problem using it for Limited?I believe that the X5 has just got approved for Production as long as it has the magwell removed.
it is showing on the list now also
