.357 Mag vs .45 Colt
The .357 Magnum vs .45 Colt comparison matches two legendary revolver cartridges with very different personalities. The .357 Magnum (125gr JHP at 1500 fps) delivers 479 ft-lbs at 50 yards through velocity, while the .45 Colt (185gr FTX at 920 fps) produces 311 ft-lbs with a larger, slower bullet. The magnum penetrates 18.0-18.6 inches, exceeding FBI recommendations, while the .45 Colt reaches 10.4-10.6 inches. Recoil differs noticeably at 9.11 ft-lbs for the magnum versus 7.01 ft-lbs for the .45 Colt. Modern strong-frame revolvers can handle +P .45 Colt loads that close the power gap. Performance varies with ammunition selection and firearm platform.
