From CMMG:

CMMG spent years innovating the AR platform with the patented Radial Delayed Blowback operating system that has revolutionized the industry. The addition of the Mk17, chambered in 9mm, shows CMMG’s commitment to never settling. Accepting Sig Sauer™ M17 P320 magazines, the Mk17 is available in both BANSHEE and RESOLUTE configurations. Pair the BANSHEE or RESOLUTE with your existing M17/P320 and you have the convenience of magazine interchangeability.

Staying true to its innovative and industry-leading values, CMMG brings to market the Mk17 on the heels of the U.S. Army and Marine Corps adoption of the Sig Sauer M17/M18 service pistols. In November of 2019, Sig Sauer delivered its 100,000th M17/M18 handgun to the U.S. military and the number continues to rise. Those familiar with the platform now have a personal defense firearm (PDW) at their disposal. As hundreds of thousands of service members adopt a new pistol platform over the next 20-30 years, the CMMG Mk17 will be a great pairing to add to their arsenal.

 

For personal defense, the Mk17 is offered in the BANSHEE configuration of AR pistols and short-barreled rifles with various barrel lengths. For the competitive shooter, the Mk17 comes in CMMG’s RESOLUTE line of 16-inch barreled rifles.

The BANSHEE is offered as a pistol or short barreled rifle with barrel lengths of 5 inches or 8 inches, while RESOLUTE rifles comes with a 16 inch barrel. Both the BANSHEE and RESOLUTE feature Last Round Bolt Hold Open.

Each Mk17 ships with one 21-round magazine and a retail price ranging from $1,199.95 to $1,549.95 for the BANSHEE and $1,299.95 to $1,799.95 for the RESOLUTE (depending on series).

On all CMMG BANSHEE and RESOLUTE 300 Series firearms, consumers can choose from ten Cerakote colors at no additional cost. Both the 100 and 200 Series offer Cerakote for the complete firearm for an additional $150 per model.

  1. “…personal defense firearm (PDW)…”
    hmmm…
    i’ve shot their mutante; very solid.
    i’d like a banshee in 10mm and then there’s the two large part.
    still, not a mouth puker.

  2. Not really understanding the purpose with a barrel length only marginally longer than a pistol on the super shorty. Little if any gained in velocity. Stability of the platform versus pistol, to be sure. Otherwise?

    Assuming the price is roughly what the Banshee series has traditionally been, I don’t see what’s desirable over a PDW conversion based on a pistol platform, outside of improved ergo’s on ancillary controls.

    • Agreed, 9×39. Even a modest increase from 5″ to 9″ would at least do something to improve muzzle velocity/energy, while allowing for mobility in tight CQB environments.

      I’ve considered the option of building out one of Banshees with my last unused AR lower, but the complete upper is a bit pricey. If I didn’t already have some ARs and wanted to build a go-to gun, I’d probably do it. But not at current prices. I already have guns for every conceivable activity I’d ever possibly engage in.

      • Wish I was there Haz, but I still have a few I need to acquire, under the gun for every occasion rule. Anyway, what AA system did you get? :p

    • It has better stability, sling ability, longer sight radius, and the ability to mount optics over a pistol. The shorter barrel also retains a lot of the maneuverability of a pistol, even with a suppressor attached. A long barrel would give you an even longer sight radius and faster velocity if the powder is still burning, but that may not be useful in a building. You then have the ability for have a primary weapon with a holstered backup that use the same magazines.

  3. I’m noticing a few Sig magazine compatible arms. The Taurus G3C takes Sig P226 mags.

    I understand the need to latch onto volume mags. The raked Glock grip angle must be a disadvantage to designs with the mag forward of the grip.

    This is an opportunity for some manufacturer (say S&W) to allow use of their mags to increase acceptance. As a Sig owner, I know mags aren’t cheap. Good, not cheap… So as an engineer, I see a market.

      • …19 and 30 round…what?…

        Do you mean standard 17-rd mags with +2 extensions to get to 19? I have Magpul 25-rounders, but am only aware of 33-rounders with the Glock name. Where did you find the 30s?

        • Glock factory 19x mags have 19rds but it is with an extension. Glock now has 24rd 9mm mags also, no 30’s that I know of.

  4. This is a great, fun, economical….

    Or it was before 9mm went to .50-.80 a round. I’m still getting 7.62×39 for $280 a 1000 case online and 12 gauge #8 federal for $22 a 100 Walmart so firearms chambered in those are the only thing I have any interest in these days. My 17,000 rounds of 9mm is earmarked for the guns I already own.

    • I have to agree.
      CMMG has some excellent choices if you like the AR-style. Marginally extending the short-range of a semi-auto 9mm isn’t for me. That said, I really do like their upper conversions, especially the Grendel.

    • See, that’s my issue, 30-06 or .308? I’ve got a lead on a, some would consider sacrilegious offering I’ve been debating for years. A bullpup chassis for either model, probably makes most peoples head azzplode ’round here.
