As BryanP mentioned, the link is to a 220 with the SA/DA trigger, the more traditional 220 variant. CDNN Sports had a run of single action only Compacts made. The full size 220s have also come single action only.
Sadly, SIG's "to hell and back" reliability has gone for a ride in the last five years.
rduckwor --Are you referring to the more traditional Sigs like the 220 and 226 or are you referring to the newer offerings like the 1911 line and the P238? I know these latter offerings had some teething issues.
