Addressing the inherent muzzle flip and snappy recoil impulses characteristic of micro-compact handguns, Herrington Arms has officially launched its updated HC43 V2 Compensator tailored specifically for the Glock 43, 43X, and Glock 48 ecosystem. Featuring a fresh aesthetic facelift aligned with Herrington’s latest generation of full-size pistol comps, the HC43 V2 delivers flat-shooting performance without requiring aftermarket recoil spring modifications.
Core Technical Specifications
- Platform Compatibility: Engineered for Glock 43, 43X, 43X MOS, and Glock 48 / 48 MOS variants with 1/2×28 threaded barrels (also compatible with Shadow Systems CR920 and PSA Micro Dagger frameworks).
- Variant Options: Available in “Fins” configuration (contoured to wrap around OEM Glock 43X/48 bullnose factory slides for a seamless look) and “No Fins” configuration (flat rear profile for standard G43 and aftermarket flat slides).
- Chassis Metallurgy: Precision-machined from high-strength 7075 aircraft-grade aluminum.
- Finish Options: Mil-Spec Type III Black Anodized or Flat Dark Earth (FDE) Cerakote.
- Length & Weight: Ultra-compact overall length of 0.87 inches; featherlight weight of roughly 0.7 oz.
- MSRP: ~$94.99
Mechanical Engineering & Metallurgy Science
The primary engineering objective of the HC43 V2 is to redirect propellant gases upward to aggressively mitigate muzzle climb while adding virtually zero front-end weight or rotational inertia to the reciprocating barrel assembly.
Constructed from 7075-T6 aluminum, the compensator achieves an exceptional strength-to-weight ratio. This ensures that the lightweight slide velocity of subcompact 9mm handguns remains balanced, allowing the weapon to cycle reliably even on factory recoil spring assemblies. The dual set-screw retention system—secured via included steel 8-32 set screws and medium-strength threadlocker (Loctite 243)—locks the unit down solidly against the 1/2×28 barrel shoulder without stripping under high thermal and pressure cycles.
Integration & Practical Utility
Beyond its functional muzzle-flip reduction (tested internally to drastically cut vertical string dispersion), the HC43 V2 excels in holster compatibility. Because of its slim profile and compact 0.87-inch footprint, the compensator readily fits into most open-bottom or closed-bottom duty and concealed carry holsters (such as Tier 1 Concealed, Safariland, and Sierra Defense rigs) without requiring custom open-muzzle modifications.
Concluding Assessment
The Herrington Arms HC43 V2 Compensator is an expertly engineered upgrade for slimline Glock enthusiasts. By combining robust 7075 aluminum metallurgy, choice-driven slide contouring (Fins vs. No Fins), and reliable stock-spring compatibility, it transforms a snappy micro-compact into a flat-shooting tactical asset.
