Lehigh Defense Xtreme Defense .45 ACP 135-grain Fluid Transfer Monolithic ammunition (brand part no. LA45-135-XD) trades the traditional hollow point for a solid copper bullet engineered to hydraulically wound rather than mechanically expand. Lehigh Defense cuts radial flutes into the nose that force hydraulic energy inward on impact, then release it outward as high-pressure spikes that cause severe, wide-reaching tissue damage. Because the bullet stays solid instead of expanding, its nose geometry drives deep, straight-line penetration and a wound cavity diameter that exceeds many conventional expanding bullets. That same solid copper construction makes the round barrier-blind, holding its performance after punching through drywall or heavy clothing rather than clogging and failing to open like a traditional hollow point. Xtreme Defense earns its name by hitting exactly as hard whether the first thing it meets is bare tissue or a wall.
Key Specifications
- The chambering is .45 ACP, a long-standing defensive caliber known for a wide bullet diameter and stopping power.
- The bullet weighs 135 grains, lighter than standard .45 ACP loads, which helps drive higher velocity into the fluted nose.
- The bullet is a Fluid Transfer Monolithic, a solid copper design built to wound hydraulically instead of expanding mechanically.
- Radial flutes in the nose force hydraulic energy inward, then outward, creating high-pressure spikes that cause severe tissue damage well beyond the bullet’s diameter.
- The nose geometry drives deep, straight-line penetration, producing a wound cavity diameter that exceeds many expanding bullets.
- Because it is solid copper, the bullet stays barrier-blind, punching through drywall or heavy clothing without losing performance, and it is lead-free.
- Cases are made of brass, giving consistent extraction and chambering.
- Each box holds 20 rounds, enough to load several magazines for carry and practice.
- Boxes ship 10 to a case, totaling 200 rounds for shooters who want to stock up.
- Each round costs about $1.82, reflecting the premium solid copper construction.
Frequently Asked Questions
Does the Fluid Transfer Monolithic bullet expand like a hollow point? No, it stays solid and instead uses fluted radial cuts to transfer hydraulic energy outward, creating a wound cavity without traditional expansion.
Will this round still perform after passing through a barrier? Yes, because the bullet is solid copper rather than a hollow point, barriers like drywall or heavy clothing do not degrade its penetration the way they can with expanding bullets.
Is this bullet lead-free? Yes, the Fluid Transfer Monolithic is machined from solid copper, making it a lead-free defensive option.
