After a great deal of trial and error and tens of thousands of rounds in testing, it's finally ready. Now, instead of parting together a complete DEM fire control group for your Glock, we've done it for you. The heart is the Gunfighter Trigger™, combined with a polished trigger bar. The trigger housing is complete with a DEM 3.5 connector and trigger return spring. We have rounded it out with a TiN or DLC coated striker, 5lb striker spring and a firing pin safety with spring.
