Whereas each cartridges will be difficult to handle, the .40 S&W could be simpler to regulate throughout fast firing. Nonetheless, this depends upon numerous components, together with the load, the particular handgun, and shooter expertise.
Disadvantages for Bear Protection
One potential drawback of the .40 S&W for bear protection is that it might have a decrease muzzle velocity than the .357 SIG, particularly with sure hundreds. In a direct comparability, a .357 SIG with the fitting load can generate extra vitality than a .40 S&W. This issues by way of penetration, but when applicable bullets are utilized in both cartridge, it might grow to be much less important.
A Direct Comparability: .357 SIG vs .40 S&W
Ballistic Comparability
To find out which cartridge is best for bear protection, a direct comparability is required.
Function | .357 SIG (Instance: 125gr Onerous Forged) | .40 S&W (Instance: 180gr Onerous Forged)
|—|—|—|
| Bullet Weight | 125 grains | 180 grains |
| Muzzle Velocity (approx.) | 1400 fps | 1000 fps |
| Muzzle Vitality (approx.) | 544 ft-lbs | 400 ft-lbs |
| Estimated Penetration | Good | Doubtlessly good (relying on load) |
