Want a simple yet effective upgrade you can give the trigger of your Glock® or Glock® compatible build to greatly improve its performance? Say good-bye to that nasty, sloppy-feeling OEM trigger pull, and say hello 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 yield an instantly noticeable difference in your pistol's trigger pull. It'll give you 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 try to guess when you'll reset and also so there's no need to regain any additional unneeded take-up. As an added perk, 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
