Robust investment cast - CNC machined 316 Stainless Steel shot engine mechanism with hybrid Stainless Steel/Kevlar reinforced *Acetyl trigger eliminating the problem of **Galling ensuring a smooth and consistent trigger pull. Fits directly into all Holt series speargun handles.

All stainless steel construction and pivot points eliminating internal deformation under load.

Extra heavy duty 8mm thick 316 Stainless Steel Sear.

Smooth spear engagement and trigger pull due to the shot engine cassette profile, geometry, polished SS components and hybrid trigger

Wide mouth allowing the use of spears up to 10mm diameter and easy flushing of the mechanism internals

*Acetyl, also known as POM is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. The addition of Kevlar fiber further enhances strength and durability.

**Galling is a form of wear caused by adhesion between sliding surfaces. When a material galls, some of it is pulled away with the contacting surface. Stainless Steel is particularly susceptible to galling, it literally cannabises itself when rubbed together under load causing difficult and inconsistent trigger pull.
