I just came across this thread during my search for a CHP Commemorative Model 68. I've read the post as to why the CHP issued the .38 instead of the .357. I was on the CHP for 30 years and was issued the model 67. We had a choice of either the Model 67 4", or the Model 68 6". I chose the 4" so it did not hit the seat while while on patrol and push up on my hip. I chose not to use a swivel holster that would prevent the 6" from pushing up into my hip while driving all day. I read we were limited to the .38 because then Gov Brown thought we would hurt too many people with the .357. All I know is the weapons staff taught us to shoot to kill. We could carry a .357 from an approved list of guns, but we were responsible for the purchase and repairs. I eventually went with a 4" Model 686.
