Beefy and comfortable - IMI Defense FSG1 Front Support Grip

This angled grip is possibly the best one I've obtained compared to the other grips used. Its length and width are broad enough to cup into your hand without trying to get that specific position on your said hand. Almost a natural feeling fit with the angle being perfect enough to feel supportive in the handling of your weapon.

Fitting it upon your picatinny will be a slight hassle, however. The FSG1 will fight you here and there because of the tight fit, but giving it some encouragement shall work and after such, will not be moving anywhere at all. The foregrip also uses a single screw to keep itself planted.
