As first reported midweek by SIGforum.com, SIG Sauer has announced that a 10mm version of their venerable P220 will be released at the SHOT Show in January.

The fascination with a 10mm P220 first started with Bruce Gray of Grayguns, Inc, who accepted a challenge that the P220 10mm conversion “couldn’t be done”.  Bruce made limited conversion runs of all steel P220 .45 ACP pistols to 10mm.  This was a painstaking task as it took quite a bit to get the pistol chambered in .45 ACP to run the 10mm reliably.

The P220/10 will be have both SAO and DA/SA configurations, and will be available in 4.25 and 5 inch lengths.  It will be based upon their all steel P220 Elite series of pistols as it is being reported.
