Liberty Ammo Performance Series comparison – Sig Sauer

News Release

Bradenton, FL, October 10, 2023

Liberty Ammunition continues the “Comparison Series” with statistical comparison to Sig Elite V-Crown personal defense ammunition.

Gary Ramey – CEO of Liberty Ammunition noted “Sig is a premier manufacturer of firearms with a broad line of ammunition. But when it comes to self-defense ammo performance, Liberty Ammunition is lighter to carry and hits harder. A lot harder.”

Ramey added “Bullet weight is a core reason some departments are doing T&E with Liberty Ammo. For key self-defense calibers like .380, 9mm and 45 ACP, Liberty is not only lighter to carry, but faster and hits harder. Liberty’s energy is not only higher, but the bullet rupture delivers all the energy and that is critical.”


Liberty Civil Defense is 60% lighter and with hits with 24% more energy than Sig.

Liberty OverWatch is 42% lighter and hits with 26% more energy than Sig.

If you like slow and soft-hitting ammo, the choice is easy.

If you want ammo that is lighter to carry and more effective, choose Liberty Ammo.

.380 cal

.380 is a core caliber with lighter weight firearms.

It makes no sense to weigh them down with heavy, slow and ineffective bullets.

Liberty has 130% the energy over Sig at 44% of the weight.

Ammo performance is critical in .380, you need as much energy as possible.

Sig Elite V Crown 90 980 192
