I did a lot of looking around to find the Cal rostered Sig P238 which is designated P238-380-TSS-CA and never found one or found a GS that has sold one. It's the added "CA" that differentiates the California rostered model from the standard issued Two-Tone model that the rest of the world can buy and from what I have gathered, I don't believe any of the "CA" models have been built or shipped. I hope a Calgunner(s) will check in and disprove my statement.
If you want to acquire a new P238 in this state, the only route is a SSE purcha$e. The good news is that they come in a huge variety of selections. I chose the HDW model-rosewood grips and all stainless steel. The shop that I purchased it from a few months ago had eight or ten different models in the case.
