Owners of the Vector SDP G3 in 9mm frequently mention the low-recoil impulse as the standout characteristic of the platform. The Vector's angled bolt design redirects recoil downward rather than backward, and shooters notice this immediately compared to a conventional pistol or carbine layout.

The 40-round magazine capacity is a draw for range use, though some owners find the larger magazine makes the pistol unwieldy for anything other than bench or supported shooting. The Arctic Delta Camo finish gets attention at the range but a minority of buyers feel it is more aesthetic than functional on a pistol-format firearm.

The threaded barrel on the Vector SDP G3 is popular with suppressor owners. The common criticism is the overall bulk and weight of the platform, which makes it a niche range pistol rather than a practical carry option. Aftermarket support for the Vector is more limited than for conventional pistols, and that limits some owners in their customization options.
