to prevent you SUCCESSFULLY suing them, for blowing up your gun with their ammo. If your barrel does NOT say .45 Super, they can establish that YOU are at fault, for stupidly using the "wrong' ammo in a gun.
.45 ACP brass is VERY capable of getting 165 gr jhp's to 1400 fps, in a 6" barrel. Dean Grennell and Mason williams proved that, 30 years ago, WITHOUT modern powders OR heavy recoil and mainsprings, and WITHOUT fully supported barrels. They just used 10.0 grs of Unique, that's all. Today's poosies "think" 165 grs at 1200 lousy fps is 'hot" in a 1911. That's a JOKE, man.
