.45 ACP vs .45 Colt
Part of our full caliber comparison chart — energy, drop and recoil for every handgun caliber side by side.
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.

.45 ACP vs .45 Colt Bullet Penetration
Comparison of estimated penetration depth in 10% ballistic gel between .45 ACP and .45 Colt at self-defense distances.
Self-Defense Ammunition Penetration
Notes:
- FBI standard for optimal penetration is 12-18 inches in 10% ballistics gel
- These penetration figures come from a model of sectional density, velocity and expansion, not from gel tests. Use them to compare the two calibers, not as a measured result.
- Actual results may vary depending on clothing barriers and other factors

Comparing recoil energy and impulse between .45 ACP and .45 Colt.
.45 ACP Recoil (Self-Defense Load)
.45 Colt Recoil (Self-Defense Load)
Notes:
- Recoil calculations based on bullet weight, velocity, powder charge, and firearm weight
- Recoil energy indicates the felt force when firing the weapon
- Recoil impulse represents momentum transfer during firing
- Actual felt recoil can vary based on grip, stance, and firearm design
