The UDP-9 is a closed bolt, blowback operated system driven by our 9mm bolt carrier group and fed with standard GLOCK® 9mm magazines.
To maximize training efficiency the UDP-9 utilizes a standard AR-15 fire control group and is compatible with most all aftermarket AR-15 Mil-Spec components.
For those that carry a GLOCK® 9mm, backup comes standard without the need to carry alternate magazines and ammunition cartridges.
“Even in full-auto mode, the 4-inch steel plates at 35-plus yards were getting hit two or three times before they fell over. This indicated a good deal of control and accuracy, despite the fast rate of fire.”
