https://shopwilsoncombat.com/mobile/1911-Elite-Tactical-Magazine-9mm-Compact-9-Round-ETM-Base-Pad/productinfo/500%2D9C9/ Wilson has them listed as officer/compact length mags. I’m not sure if they will fit the box, might need some slight modification. Good to know about the full length mags possibly damaging the ejector.

What magwell and basepads are you running? I’m curious if Wilson ETM 9rd mags will fit the box, they are already extended a bit and may feed a little more reliably.
