[becket]

Hi, I posted in another forum but prob should have come here first. Anyone know the thread size for a Hi-Standard em-100, or dm-101,
Grip screw? I can just jet around the corner as Ace Hardware here has gun screws, thx

Don't know what your answer was but in my experience, most revolver-style grip screws are #5-44.
