Zenith Firearms has a new series of pistol-caliber firearms. The Modern Roller Delayed System (MRDS) PDW series takes the rifle-caliber options like the ZF-56 and adapts it to 9mm and 10mm. And before you ask, yes, they take Glock mags.


Roller Delay @ TFB:


There are two new models in the MRDS PDW family, the ZF-9 and ZF-10. The ZF-9 is the 9mm version, and the ZF-10 is chambered in 10mm. The 10mm is a little heavier, weighing in at 4.5 pounds compared to the 4-pound weight of the 9mm model. Both feed from Glock mags and the ZF-9 also offers a lower compatible with Scorpion magazines.


Both are fully ambidextrous with AR-style controls. The rear of the receiver features a picatinny rail for mounting an arm brace or stock. The top of the receiver and handguard are railed as well, and the handguard includes MLOK slots.


There is no word on pricing or availability timeframe as of writing, but you can sign up for email updates on the ZF-9 or ZF-10.

      The Kuna has one strike against it though. It uses only proprietary magazines. The fact that this one uses Glock mags will make a huge difference to anyone who uses Glock pistols.
