I got a new standard manual safety sig p365 for a good price, immediately shot it with the polymer grip and everything worked correctly. I then bought an Icarus precision hybrid grip and tried to shoot it, and discovered the trigger wouldn’t reset. I had to manually push the trigger forward for it to reset, also shaking the gun made it reset as well. Swapped it back to the polymer grip and the issue went away. Does anyone know why the Icarus grip would cause the trigger to not reset?
