I bought a Tacfire LPK lfor a G19 ast month Order #1000831. I am building a Grey Ghost Precision serialized lower (GGP branded and finished poly 80 as I am sure you know). The trigger housing is sitting up to high for the slide to clear. Have there been any other issues with those? I guess I need to return it... The Ejector actually dinged up the GGP rear slide plate.
