In the past 2 years, even police departments have been affected by the ammunition shortage. Many departments can't get what they usually prefer.
My department, the Salt Lake County (UT) Sheriffs Office, issues Federal's "Tactical Bonded" 230 gr. Plus-P jhp, catalog # LE45T1, for deputies carrying .45 ACP. Before that, it was Hydro Shock, both generations (post and no post).
The department permits deputies to purchase and carry handguns chambered for 9mm, .357 Sig, .40 S&W and .45 ACP. Detectives can carry .380 ACP on duty and all can for back-up and off-duty. Recently, we got our .38 Special snubs back for back-up and off-duty. I am not current on what we issue for the others.
