Vertec-style vertical grip of the M9A4 offers two very important benefits. First, its vertical back-strap configuration makes it easy to point the handgun to where one would normally point the index finger of the dominant hand. This instinctive pointing is highly prized by tactical shooters and makes for consistent and consistently accurate target acquisition. Also, the grips are thin and aggressively texturized while still accommodating a double-stack, 18-rd magazine. The Vertec profile grip makes trigger reach simple even for those with smaller hands and offers a more compact profile for those who choose to carry the M9A4 concealed.

Versatility and Easy Customization: One of the most salient benefits of the M9A4 is its universal decock-only (G) slide that befits the combat-oriented pistol that this new model is based upon. The M9A4 also features a removable front sight for tactical shooters who have a distinct preference in terms of sight picture, material, or construction. In addition, a variety of accessory options is possible thanks to the built-in 3-slot Picatinny rail located in front of the trigger guard, which enables the easy attachment of a variety of tactical lights, laser devices, and more.
