HB Industries CZ Scorpion EVO 3 Delta Trigger

The HB Industries Delta is the most popular shoe-only trigger upgrade for the CZ Scorpion EVO 3 because it solves two factory complaints at once. The recurve face cradles the trigger finger and keeps it centered through the long Scorpion stroke, which produces more consistent follow-up shots than the flat factory shoe. The +5mm forward position increases leverage on the factory hammer pack for a roughly 12 percent reduction in pull weight, dropping a typical factory pull from the high-8 to low-9 lb range into the upper 7s without touching the hammer or springs.

Construction is billet 6061-T6 aluminum hardcoat anodized to MIL-A-8625 Type 3, finished in Black, Burnt Orange, or Red. The Delta drops in with the included roll pin and counts toward 922R compliance. It fits every CZ Scorpion EVO 3 and EVO 3+ pistol and carbine.

Pair the Delta with the HBI Reduced Weight Trigger Spring Kit for the cheapest path to a sub-6 lb Scorpion pull. Owners who want a flat face instead of a curve can pick the Theta Forward (same +5mm offset) or Theta Stock (factory geometry) for the same price.
