If you drive a Porsche with an upgraded chipset, you must be willing to feed your auto a higher grade fuel as recommended by the manufacturer. Although the Bond Bullpup9 doesn't afford increased horsepower, torque or driving characteristics, you still glean a great satisfaction of owning this small 9mm. The ergonomics are welcome to my medium sized hand. Firing from the Bullpup9 firmly pushes the rounded, rosewood grips against the fleshy part of my palm in a platonic embrace. It just feels right! It conceals well as a pocket gun or inside the waist carry. There does exist a list of recommended ammunition to feed this beast to keep it happy. It won't ping and falter like a Porsche on a junk-food diet, but feeding a round of less than optimally crimped casing may just cause a separation of the bullet from the shell. This hasn't happened to me personally. As of this writing, Bond has included no less than 30 different "approved" self-defense types of ammo and nearly as many for range ammo. If you appreciate a run-of-the-mill, very reliable car, buy a Subaru. If you dare to step outside the box toward this beautifully crafted, anodized aircraft aluminum frame paired with a bead blasted stainless steel slide, you won't be disappointed.
