Guides: Which MP5 trigger fits
Mechanically this is the same trigger as the SEF version. The difference is the housing: a selector lever on each side, so you can work it with either hand without shifting your firing grip. That matters if you shoot from both shoulders, or run the gun with your support hand well forward on the handguard.
Three positions, safe, semi and forced reset, and one round for each separate pull of the trigger. It drops into the MP5, MP5K, SP5 and SP5K packs with no machining. The choice between this and the SEF housing is about ergonomics and the look of the gun; nothing else about the trigger changes.
