Hot on the heels of the USMC adopting the H&K M320 grenade launcher, another branch of the armed forces is on the hunt for a new weapon in a category they’ve termed as “Sub Compact Weapons”. To fulfill the requirements of the Army’s stipulations, 10 different firearms are being considered for the role of a “highly concealable sub compact weapon system capable of engaging threat personnel with a high volume of lethal and accurate fires at close range with minimal collateral damage.” The Army has already ordered samples of the following firearms for rigorous testing and evaluation:

Colt Manufacturing’s M5A Colt Modular 9mm SCW (

Beretta USA’s PMX SMG (

CMMG Ultra PDW Sub Compact Weapon

CZ-USA’s CZ Scorpion EVO 3 A1 SMG (

Zenith Firearms for Z-5RS (pictured above), Z-5P and Z-5K Sub Compact Weapons (


The other 5 contenders include the Brugger & Thomet MP9, PTR’s 9C with integrated M-LOK system, SIG Sauer’s MPX, LMT’s MARS-L9 Compact Suppressed Weapon, and Quarter Circle 10 LLC’s 5.5 CLT and 5.5 QV5 Sub Compact Weapon. As we can see, the lineup comprises a mixed bag of new and not-so-new innovations in the category of Sub Compact Weapons. The winning firearm will have to meet the US Army’s “operational need for additional concealability and lethality”, while also having the ability to attach a suppressor. Should they be unable to find a suitable firearm, the US Army stresses in its circular that “Failure to provide the selected SCW for assessment and evaluation will leave PSD (Personal Security Detail) military personnel with a capability gap which can result in increased war fighter casualties and jeopardize the success of the U.S. mission.” Let’s hope that among the evaluated firearms, the US Army will find a worthy SCW.
