Apologies if this has been posted.
Looks like Sig has tweaked the XFive a whole month after i bought mine, with a new Legion version. Looks like the primary difference is a Tungsten grip module that increases the weight to 43.5 ounces with the magazine and magwell. Take off the magwell and its right in line with the Walther steel Frame Q5 that came out in January.
