11 things you need to know about the Army's new handgun

Half a decade into its search for a new handgun, the Army has chosen Sig Sauer's P320 as its new service pistol. 

Here's what we know so far: 

• The P320, released by Sig Sauer in 2014, is a polymer striker-fired pistol, according to a statement from the gunmaker.

• The new sidearm will replace the M9 Beretta, the Army’s pistol of choice for more than 30 years, according to an Army announcement Jan. 19.

• The P320 is the first modular pistol with interchangeable grip modules that can also be adjusted in frame size and caliber by the user. 

• It can be adapted to shoot 9mm, .357 SIG and .40 S&W ammunition, according to Sig Sauer.

• Although neither the Army nor Sig Sauer announced which caliber the Army chose, media reports say the Army chose the 9mm version.
