They are priced right, and they are a proper fit. Some allen head screws are an odd size and no key fits exactly right but these fit a 3/32 allen key nice and tight. They are sort of green, not black like you would expect. I recommend starting them without the grip on the pistol to get the coating off of the threads, take them out and reinstall with the grip on.
Pros: Hex head screws
Cons: Hard to thread, wrong color
