.45 ACP vs .45 Colt
The .45 ACP vs .45 Colt comparison matches two iconic American cartridges sharing the same bore diameter but designed for different platforms. The .45 ACP (230gr JHP at 850 fps) delivers 343 ft-lbs at 50 yards while the .45 Colt (185gr FTX at 920 fps) produces 311 ft-lbs. The .45 ACP achieves optimal FBI penetration at 12.2-12.3 inches, while the .45 Colt falls slightly short at 10.4-10.6 inches with this load. Recoil runs similar with the .45 ACP at 6.06 ft-lbs and .45 Colt at 7.01 ft-lbs. Semi-auto capacity favors the ACP while the Colt offers revolver reliability. Performance varies with ammunition selection and firearm platform.

Self-Defense Ammunition Penetration
Notes:
- FBI standard for optimal penetration is 12-18 inches in 10% ballistics gel
- Our penetration data is calculated using mathematical models based on sectional density, velocity, and expansion factors. While not actual gel tests, our calculations have been validated against manufacturer test data and provide reliable estimates for comparison purposes.
- Actual results may vary depending on clothing barriers and other factors
