Upgrade the action of the trigger in your Glock® or Glock® compatible build. Go from that nasty, sloppy-feeling OEM trigger pull, to one that's smooth, has a much lighter pull weight, and has a much crisper reset.

This is the 3.5 lb Connector (gens 3 to 5) from Double Diamond. A simple yet super effective upgrade, this connector will give you an instantly noticeable difference in your pistol's trigger pull. It'll provide a consistent pull and lighten your stock trigger's pull weight from 7.5 lbs to a mere 3.5 lbs. This means you won't have to "fight with" your trigger so much to stay on target during each squeeze. For follow-up shots, it'll make your trigger's reset crisper and more pronounced, so you don't have to guess so much and also so there's no need to regain any additional unneeded take-up. Finally, the 3.5 lb Connector is coated in NP3, which provides a "dry lubricated, low friction surface that is both extremely hard and wear resistant."

Please note: The Double Diamond 3.5 lb Connector (gen 3-5) will work on any double-stack Glock® compatible models that are gens 3 through 5 only. It will not work with any of the single-stack models (42, 43, 43X, or 48).


  • Fits all double-stack gen 3, 4, and 5 Glock® compatible models (but not 42, 43, 43X, or 48).
  • Relatively easy to install
  • Reduces trigger pull from 7.5 lbs to 3.5
  • Provides crisper trigger break and reset
  • More consistent feel for each squeeze of the trigger
  • Coated in NP3 to provide smoother and more wear-resistant action
  • Facilitates more accurate shooting by decreasing trigger resistance
