Underwood Ammunition 357 Sig 124 Grain Jacketed Hollow Point Box of 20

Underwood Ammunition 357 Sig 124 Grain Jacketed Hollow Point Box of 20 delivers a traditional-weight jacketed hollow point loaded to Underwood’s characteristically high pressure and velocity standards. 124 grains sits close to the cartridge’s original service-pistol specification. This load offers a familiar balance of expansion, penetration, and recoil. Underwood loads each cartridge individually rather than on fully automated lines, which allows for tighter quality control than many mass-market brands.

Service-Weight Hollow Point Performance

As a result, this loading suits shooters who want a proven bullet weight paired with hotter velocity than typical factory ammunition. The jacketed hollow point cavity expands reliably across a broad range of impact velocities, even from shorter carry barrels. Meanwhile, the higher pressure loading gives this round more downrange energy than standard-pressure 124 grain offerings from other brands.

About This Underwood Ammunition 357 Sig 124 Grain Jacketed Hollow Point Box of 20 Load

Underwood ships this load in a standard box of 20. That makes it easy to compare against duty ammunition from major brands. Naturally, shooters transitioning from a standard-pressure carry load may notice increased recoil and muzzle flash with this hotter loading. Therefore, we recommend function-testing in your specific pistol before you adopt this round for daily concealed carry.

All loads follow SAAMI pressure and dimensional standards for safe, reliable function.
