It is not still offered. The "long model name" was P226 AL SO. It is/was offered in Europe, along with the P226 AL SO BT, which has a beaver tail. The SIG USA model code identifying it as an all-German P-226R was E26R-9-BSS-GER. They had stamped slides and internal extractors. This was around 2010. I'm looking for one too. They rarely come up for sale. They did not have MIM parts. They were made the old way with cast internals (only the E26R-9-BSS-GER aka P226 AL SO).

Update:There were multiple models of German 226 during this time frame. Here are the SIG model codes:
E26R-9-BSS-GER (pictured above) 2010, SIGLITE Night Sights, Carbon Steel slide, Internal extractor, removable breech block, Blued finish.
E26R-9-B-GER 2011, MIM parts, standard contrast (not night) sights, blackened SS slide, external extractor, non-removable breech block, E2 grips, Nitron finish.
