OK, so you tell me what you think it is if it’s not mostly .40S&W.
I recently retired from DHS and the agency still issues 9mm ammunition to a large number of agents and officers. Many carry the Sig Sauer 226 that uses the 9mm round. These guns are carried as either back up weapons or as a primary depending on the position occupied by the officer/ agent. Most everyone else carries the Sig Sauer 229 that uses the 40 S&W round. Before I left the agency I was a supervisor and signed for some very large amounts of ammunition that was delivered to the field office. Most of it was 40 S&W. I also signed for large amounts of 223, 9mm and shotgun ammo. I think that everyone should contact their elected representatives and demand an answer as to why so much ammunition is needed. I personally beleive it is designed to create a shortage of ammunition. Just another form of gun control from Obammie and company.
