My brother in law owns a 938 extreme and he has had several issues with it. FTE is the major one. First of all they say that the gun prefers 124 grain ammunition. So we tried both 115 grain and 124 grain and had the same issues with both. After looking into it I believe that Sig has a recall on the extractors for the gun. It would be worth buying one and sending it to sig just to have it fixed. If that problem is fixed I would love to own one. After shooting it several times, I thought it shot well for a good CC gun. Hope this helps.
