Does anyone know (have you tried and it worked) if a SP89 trigger group will "drop in" (just remove pins on factory SP5K, remove HK SP5K trigger group, and install SP89 group, pins back in, shoot)? Further, has anyone used a clipped and pinned MP5K compatible clone trigger group in their SP5K yet? I have done a search and got several bits of intel but wanted to know if/who has actually done and any issues if can be done as simple drop in as I am considering purchasing the SKU HKP16442 from HKParts for my SP5K SBR. Thanks
