.32 ACP vs .38 Special
Part of our full caliber comparison chart — energy, drop and recoil for every handgun caliber side by side.
The .32 ACP vs .38 Special comparison examines two options for compact carry guns. The .38 Special (125gr JHP at 900 fps) delivers 202 ft-lbs at 50 yards while the .32 ACP (60gr FTX at 1000 fps) produces 104 ft-lbs. Penetration tells the story: the .38 Special reaches 11.9-12.1 inches, near the FBI's 12-inch minimum, while the .32 ACP manages only 7.0-7.3 inches. The .32 ACP recoils at just 0.81 ft-lbs compared to the .38 Special's 2.19 ft-lbs. The .32 ACP fits the smallest semi-auto pocket pistols; the .38 Special in a snub-nose revolver offers better terminal performance at the cost of size and capacity.

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
.32 ACP vs .38 Special Recoil
Comparing recoil energy and impulse between .32 ACP and .38 Special.
.32 ACP Recoil (Self-Defense Load)
.38 Special 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
