Authentic Pearl grips/stocks would not likely survive the first discharge.
I don't know. These have held up for some time I think. I admit, I don't know how long though. I also admit that the Colt is a 32, which isn't noted for it's wrist shattering recoil, but I have fired it a few times.
Note: There is a small chunk broken out of the bottom of the grip, but the pistol is almost 100 years old, so it may have been banged around a bit.
