Double Tap is known for their fast shooting ammo. I just got a box of that 9mm in to try also, but have not shot any yet. It should work well. It is faster and has more energy than even the Winchester +p+ 127 grain load. This should bring the 9mm into 357 sig levels as most factory ammo is 125 at 1350fps.
I picked up an assortment of Double Tap to try as I have read good reviews of the ammo. Good luck with your purchase.
