I've seen some instances where an improper installation of grips to frames (either a loose installation, or through wear of those parts over time) causes the frame to sit further away from the grip than it should. The result is the the sear sitting too high, and getting caught on the middle prong of the leaf spring - this can create temporary or permanent full auto fire until corrected.

I've found that stripped grip screw holes can also cause the grip to sit too low, resulting in low fps.
