Liberty SPIKE 2.0: Brass-Cased 380 and 9mm at 1,500 fps

Liberty Ammunition launched SPIKE 2.0 in .380 ACP and 9mm on June 11, 2026, with one purpose: fix the feeding issues the original SPIKE had in pocket .380 pistols. The projectile is unchanged. SPIKE 2.0 carries the same 55-grain monolithic copper hollow point with a center spike that drives expansion, runs at 1,500 fps from a short barrel, and carries 275 ft-lbs of muzzle energy. What changed is the case. Liberty replaced the original SPIKE's patented NAS3 nickel-aluminum-steel two-piece case with a conventional one-piece brass case sized to feed and seal reliably in pocket .380 pistols with unsupported chambers.

That fix matters. The Ruger LCP, LCP Max, S&W Bodyguard 380, Bodyguard 2.0 in .380, Glock 42, and Sig P238 all use unsupported or partially supported chambers, a design choice that keeps frames slim and slides short. Two-piece cases under full-velocity loads can swell or short-stroke in those guns, and Liberty's own product page on the original SPIKE now reads, “not recommended for un-supported chambers. Buy 2.0 for those.” SPIKE 2.0 is the version that belongs in a carry pistol. For a head-to-head ranked comparison against Federal HST, Hornady Critical Defense, Speer Gold Dot, and the rest of the defensive .380 market, see our best 380 ACP ammo guide.

Specs below reflect manufacturer numbers as of June 17, 2026. Independent gel testing of SPIKE 2.0 specifically has not yet been published; numbers for the original SPIKE projectile transfer because the bullet is unchanged.

Pocket .380 pistols use unsupported chambers because that geometry keeps the slide short and the frame slim. A fully supported chamber wraps the case head in steel; an unsupported chamber leaves a portion of the case web exposed above the feed ramp. Brass flows under pressure and seals against the chamber walls without issue. Liberty's original NAS3 case was a two-piece design with a steel head, aluminum body, and nickel finish, engineered for weight savings and consistent ignition. That two-piece interface, paired with a 1,500 fps load and an unsupported chamber head, was the failure mode.

Switching to a one-piece brass case eliminates the seam, lets the case obturate normally against the chamber wall, and brings the cartridge back into the operating envelope every other major .380 defensive load works inside. The trade-off is weight. Brass-cased SPIKE 2.0 is slightly heavier per round than the NAS3-cased original, which matters for full magazines in a 9.4-ounce LCP Max but not for the physics of the bullet itself.

The result is a .380 load that runs in the pistols people actually carry .380 ACP in. The Bodyguard 2.0 and LCP Max dominate the modern pocket .380 segment, and both use unsupported chambers. Putting SPIKE 2.0 in either of those guns does what the original SPIKE could not.

Liberty's wound-mechanism story on SPIKE has two parts. The first is fragmentation. The hollow point petals open and shear off in a 3-inch-wide cone to roughly 5 inches of depth, cutting multiple parallel wound channels in soft tissue. The second is the core. The central spike and remaining bullet base continue forward to a stated 13 inches through 12 layers of denim, keeping the round inside the FBI 12 to 18 inch penetration window through heavy clothing. That is the same window Federal HST 99gr lives in at 1,030 fps from a longer, slower load.

Liberty's own comparison numbers: SPIKE hits 43 percent harder than Sig V-Crown Elite and 37 percent harder than Hornady Critical Defense in head-to-head .380 testing, on a kinetic-energy basis. That math is straightforward at 275 ft-lbs versus 200 and 199 ft-lbs respectively. Whether that translates to better real-world terminal performance depends on how the bullet behaves through heavy clothing, into bone, and against intermediate barriers. Independent gel testing of SPIKE 2.0 specifically has not yet been published. The original SPIKE projectile has, and early ballistic gel tests showed the fragmentation cone and core penetration Liberty advertises.

The realistic comparison: SPIKE 2.0 in .380 will hit harder and faster than every conventional jacketed hollow point in the category. It will penetrate as deep as Federal HST through clothing, by Liberty's numbers, but the wound-channel geometry is different. Fragmenting copper petals spread shallow energy in a wider cone; bonded JHPs concentrate energy on the bullet's expanded mushroom at the end of a deeper, narrower channel. Pick the load that runs reliably in your gun first, then optimize on terminal preference. For the full bullet-construction comparison across calibers, see our .380 vs 9mm vs .45 ACP guide.

The defensive .380 market settled into a small group of dominant loads over the last decade: Federal HST 99gr, Hornady Critical Defense 90gr FTX, Speer Gold Dot 90gr, Federal Hydra-Shok Deep, and Underwood Xtreme Defender. SPIKE 2.0 enters this bracket as the velocity outlier. Every other load on that list runs between 950 and 1,050 fps. SPIKE 2.0 runs 50 percent faster.

Velocity is not free. Faster, lighter bullets generally penetrate less than slower, heavier ones on a sectional-density basis, which is why most defensive .380 loads push 90 to 99 grain. Liberty's answer is the copper construction. The monolithic spike-tipped bullet retains its base through deep tissue while the petals expand and shed early, and the 13-inch published penetration through 12 layers of denim is at the upper end of the FBI window.

The realistic pick order for a carry .380 in 2026 if your pistol has an unsupported chamber:

If reliable feeding is the priority, Federal HST is still the gold standard with the longest documented track record across pocket pistols. If maximum kinetic energy and fragmentation is the priority, SPIKE 2.0 is now the load to compare. If you want a non-expanding solid-copper option that sidesteps hollow point clogging entirely, Underwood Xtreme Defender is the closest peer. Match the load to the gun and function-test 100 rounds minimum before carrying it.

The 9mm SPIKE 2.0 carries the same brass case and 55-grain monolithic copper projectile, sized for 9mm Luger. Liberty has not published .380-style ballistic comparison numbers for the 9mm yet, and independent gel tests have not yet appeared for the 2.0 variant in 9mm specifically. The original 9mm SPIKE projectile is positioned by Liberty alongside the company's Overwatch line as a high-velocity fragmenting defensive load.

For 9mm carry pistols, the brass case fix is less critical because most modern 9mm concealed-carry guns use fully supported or near-supported chambers. The Sig P365, Glock 43X, Hellcat, and S&W Shield Plus all support the case head adequately for conventional brass-cased loads. The 9mm SPIKE 2.0 is a parallel SKU more than a fix for a known issue. If you are choosing a 9mm defensive load for an EDC pistol, our ranked best 9mm self-defense ammo guide covers the dominant duty and carry options.

SPIKE 2.0 is the version of Liberty's flagship pocket-pistol load that actually fits the gun most people carry .380 in. The brass case fixes the only legitimate criticism of the original NAS3-cased SPIKE, the 55-grain copper projectile still hits faster and harder than anything else in the category, and Liberty's published penetration depth keeps it inside the FBI 12-18 inch window through heavy clothing. At $45.99 for a 20-round box it sits in the same price tier as Federal HST.

For Ruger LCP Max, Bodyguard 2.0, Glock 42, and Sig P238 carriers who tried the original SPIKE and ran into feeding problems, 2.0 is the answer. For new buyers shopping defensive .380 for the first time, SPIKE 2.0 belongs on the function-test shortlist alongside Federal HST and Hornady Critical Defense.
