Assuming you mean U.S. Marshals, according to usmarshals.gov, it's a Glock .40 caliber, but it didn't specify which model. I know a guy that is a marshal, and if I talk to him in the near future, I'll ask.
Colt 44
Luger 9mm pistol
The CIA does not have a standard issue handgun. This is because most agents do not see combat. the firearms they do issue are issued on a basis of preference of the operator and geography (meaning they are issued for a specific purpose). No standard firearms.
Beretta model 92. It is a 9mm cal.
The standard issue handgun of the philippine army is the m1911a1 .45 acp. But nowadays most filipino soldiers are buying their own side-arms maybe because of shortages.
I'm reasonably sure it's the Glock 23 for most agents.
Handguns are standard issue now. -------------------------------- However, for PURCHASE of a handgun, there is no exception in Federal law for members of the military- they cannot buy a handgun if under 21.
The Los Angeles Police Department's (LAPD) standard issue handgun is the Glock 17 Gen5. This firearm is a 9mm semi-automatic pistol known for its reliability and accuracy. It has been chosen for its durability, ease of use, and consistent performance by the LAPD.
That is the correct spelling of the handgun model Beretta M9 (standard issue 9mm pistol of the US armed forces).
I believe the current standard issue is a Glock 23, but I'm not sure. Someone else please correct me if I'm wrong.
The Luger was a standard issue sidearm in WW1. The P-38 pistol replaced it in WW2.
I don't know about other countries, but in the U.S. the standard issue handgun is the Beretta M9 which is basically the same as a 92FS. Some units in the military such as the SEALs, use other guns...Sig 226, I believe.
