Well, do they?  I'm betting no because I cannot find anything that says they do but I would like to hear from you guys for the final word.  My next pistol will be a sig because I'm in love with the way they point and how balanced they feel in my hand.  That is all of them except for the POS Pro.  That thing feels like a cheap piece of dung.  No wonder it's half the price of a regular sig.  I'm really leaning towards the P220 if there is no 10mm.  Thanks

Never have.

Not many pistol companies make pistols chambered in 10mm anymore.  But no Sig does not presently make 10mm pistols, and in the past their have been no records that they have produced one.

Combat_Jack and Mb121 are correct.  However, if SIG ever does make a 10mm, the line will form behind me.
