I've watched several YouTube videos showing that their AWD patented system out performs all other AWD systems by far. Our 2001 Forester w/Pirelli tires will handle all the snow Iowa has dealt us.
Have you considered a Crimson Trace laser ? You don't have to align your rear and front sight with a C/T . Just put the beam where you want the bullet to go. You do have to sight in the laser however. No big deal at all. YouTube videos are helpful.
I buy once fired brass online. I'm not that good that I could ever tell the difference between once fired and new brass. I've had good luck loading Power Pistol from Alliant with 124 gr FMJ from Precision Delta.
I liked mine so well, I bought my first Crimson Trace (green) for it. It's loaded with 124 gr HST ammo and I feel the combination is good enough I'm betting my life on it. Complete confidence.
