Why This Wins for Defense Carry
Having run 500+ rounds through Glock 19s and SIG P320s at our Spring TX range, the Winchester Defender consistently delivers 1,200 fps muzzle velocity without excessive recoil. The bonded jacket prevents separation – something I’ve seen firsthand when testing barrier penetration against denim and drywall.
