Sounds like St. Louis, in reverse. Fortunately among most local PD here, the Safariland ALS series holsters seem to be the norm. I have yet to see a SERPA on anyone in uniform.
Unfortunately, the same cannot be said of our local group of OC retards, among which the SERPA is the tacticool holster of choice, bar none. OC has become a real big issue in the area over the past year or so, and just as I have yet to see a cop with one, I have yet to see an OC'r without one.
