DoubleTap Controlled Expansion .40 S&W 135 Grain Jacketed Hollow Point (MPN: 40135CE)
Concealed carry permit holders, law enforcement professionals, and personal defense strategists operating the .40 S&W platform often seek a defensive cartridge that minimizes the sharp, snappy recoil typical of standard 180-grain duty rounds while maximizing kinetic energy transfer downrange. DoubleTap Ammunition engineered their Controlled Expansion 135-grain Jacketed Hollow Point (JHP) load (MPN: 40135CE) specifically to optimize this ballistic performance curve. Purpose-built to push high-velocity energy out of service and compact duty handguns, this high-performance defensive round delivers explosive hydrostatic shock, rapid terminal expansion, and reduced pass-through risk.
At the center of DoubleTap’s 40135CE cartridge is a premium 135-grain jacketed hollow point projectile built for controlled deformation. The notched copper jacket encapsulates a lead core engineered with a specialized nose cavity. Upon striking fluid tissue at high speed, the jacket controls mushrooming into wide, uniform petals without shedding mass or fragmenting prematurely. This design transfers maximum kinetic foot-pounds of energy into target vital zones within standard defensive penetration depths, preventing dangerous over-penetration in urban and home defense environments.
Out on the range or in high-stress defensive scenarios, expect authoritative slide cycling, crisp ignition, and flat short-to-medium-range trajectories. Launching its lightweight 135-grain JHP projectile at a blistering muzzle velocity of approximately 1,375 FPS (and up to 1,450 FPS out of longer 4.5-inch duty barrels), this round generates over 560 ft-lbs of muzzle energy. DoubleTap hand-crafts these cartridges in the USA using factory-fresh, heavy-walled reloadable brass cases charged with low-flash propellants and non-corrosive boxer primers, ensuring reliable cycling across steep feed ramps and preserved night vision in low-light tactical encounters.
Armorer Bench Notes & Technical Maintenance Guidance
Shipping Restrictions: Ammunition sales are strictly regulated. Check all state and local laws prior to ordering. Cannot ship to PO Boxes, APO/FPO addresses, or internationally. Must ship via ORM-D / Hazardous Ground transport.
Armorer Tip: Lightweight, high-velocity 135gr .40 S&W cartridges generate rapid slide velocities. While felt recoil is lighter than heavy 180gr loads, the slide moves with increased speed. When shooting high volumes of high-velocity ammunition through semi-automatic pistols (such as Glock 22/23, Smith & Wesson M&P40, or Sig Sauer P229), inspect your recoil spring assembly every 3,000 to 5,000 rounds to prevent frame battering and ensure consistent lockup.
