Lehigh Defense Xtreme Defense .40 S&W 115-grain Fluid Transfer Monolithic ammunition (part no. LA40-115-XD) takes an entirely different approach to defensive bullet design than a traditional hollow point. Lehigh Defense machines this 115-grain bullet from solid copper with a fluted nose rather than a hollow cavity, so it cannot clog with clothing or barrier material the way a conventional hollow point can. On impact, the flutes channel tissue and fluid around the bullet, driving controlled expansion through hydraulic pressure rather than a jacket peeling open. That light-for-caliber weight also drives noticeably higher velocity than standard-weight .40 S&W defensive loads. In handgun ammunition built around a clog-proof design, this is a genuinely different take on personal defense.
Key Specifications
- The chambering is .40 S&W, a widely carried duty and defensive handgun cartridge.
- The bullet weighs 115 grains, lighter than standard .40 S&W loads for increased velocity.
- The bullet is a solid-copper Fluid Transfer Monolithic (FTM) design, with no hollow cavity to clog.
- Fluted grooves in the nose channel tissue and fluid around the bullet on impact, driving expansion hydraulically.
- The cases are brass, and each box holds 20 rounds, shipped 10 boxes to the case.
- Cost runs about $1.82 per round for a purpose-engineered defensive bullet.
- This load chambers and fires in any semi-automatic pistol built for .40 S&W, with no special modification required.
- The solid-copper build makes this load compliant in areas that restrict lead ammunition.
- Lehigh Defense machines every FTM bullet from a single piece of copper rather than assembling a jacket and core.
Frequently Asked Questions
How does a fluted bullet expand without a hollow point cavity? The flutes cut into the nose channel tissue and fluid around the bullet as it penetrates, creating a hydraulic effect that drives expansion without relying on a cavity that could clog.
What is the advantage of a design that cannot clog? Traditional hollow points can lose effectiveness if clothing or other material packs into the cavity before reaching tissue, while a fluted monolithic design has no cavity to clog in the first place.
