A close clone to HK's VP9, the pistol's ergonomics is slightly different and there are some small visual design changes. Otherwise, internally, it works similar to the VP9 pistol itself, due to the size of the mag grip, it was not able to accept VP9 magazines.
The functionality of the pistol is like most modern pistol, it has an ambidexterious safety, a slide release/lock and mag release of what you expect. The slide accepts vanilla RMR. Of course, it accepts stock, any muzzle device and also another rail below.
