A '2011' that took $30 XD magazines vs $99 2011 mags would be pretty cool though.
Theres even a factory 140mm 22rd mag for the XDM for $30....
The biggest weakness of the 2011 platform is the expensive and iffy reliability of the 2011 magazine, as well as the .38 Super dimensions.
Going with a regular, existing high cap 9x19 mag (ala Wilson EDC X9) would be a smart move.
