Boonville, MO-(Ammoland.com)- CMMG tames the snappy .40 S&W by pairing it with its (patent pending) Radial Delayed Blowback (RDB) operating system in its BANSHEE and RESOLUTE models.

CMMG’s innovative Radial Delayed Blowback operating system incorporates a mechanical delay that forces the bolt to rotate and unlock, momentarily slowing the bolt carrier group, which allows chamber pressures to fall before cycling. This mechanical delay allows for reliable function with a wide variety of ammunition and removes the need for a heavy bolt, buffer and spring required in direct blowback systems. Radial Delayed Blowback significantly cuts felt recoil, directs more gas down the barrel resulting in cleaner function and real advantages when using a suppressor.

Unlike most Pistol Caliber Carbines (PCC’s), CMMG rifles and pistols that feed from Glock magazines include the shooter-friendly Last Round Bolt Hold Open feature (patent pending).

A BANSHEE or RESOLUTE in .40 S&W is the perfect complement to millions of Glock .40 caliber handguns currently in the hands of American consumers and law enforcement.

The .40 S&W will be offered in both CMMG’s BANSHEE and RESOLUTE line of firearms, with barrel lengths of 5 inches, 8 inches and 16 inches. Starting at 4 pounds 12 ounces and an overall length of just 19.2 inches. One 22-round factory Glock .40 S&W magazine included where allowed.

    1. If this gets made in 10mm, I’ll have FINALLY found what I’ve been looking for. I haven’t bought anything currently out there because nothing had the combination of features that this does. I just couldn’t bring myself to buy some heavy straight blowback 10mm.

    2. That’s the WORST video I’ve ever seen!!
      Guy doesn’t even bring a screwdriver to a sight in??!!
      Worst choice of promotional material I’ve seen in this site ever.
      The gun itself is a dandy and in either 10mm, .40 or .45 seems a good choice. Although I am curious what @hardshell is getting at.

    3. The shortest barrel version would make for a VERY interesting firearm with a good suppressor. Add a binary trigger and you’ve got a poor man’s non-NFA HKMP5SD, which would be a very nice home defense firearm.

      1. Well just buy two then. I just bought a Mini Roni for my Glock including a red dot sight for $229.
        I would love to have one of the 40 cal pistols mentioned in the article

      2. I think your missing the point. The comparison here is the HK MP5 – it seems CMMG has effectively developed Americas MP5. The Banshee has Radial Delayed Blowback which accomplishes the same thing that Hk’s Roller Delayed Lock but does so without the expense of the HK system. So the Banshee uses familiar AR15 controls, uses Glock magazines which are inexpensive and available, is lighter, has last round bolt hold open and is $1000 cheaper than a quality MP5 clone. The CMMG Banshee will be my next firearm. Only question is – 9mm, 5.7×28 or 45ACP?

    4. The conditions in battle field are extremely dangerous. While the soldiers and infantry moving in an armored personnel carrier are relatively safe from explosive IEDs and other explosives, they are increasingly vulnerable to the small and heavy ammunition fire when they charge in the open.
