Great product. Highly recommend using with hex drive bushing and both bushing o-ring and screw o-ring.

You can install them, take them off and they won't have a burr on them.

Good fit for a Kimber Ultra-carry II

I had some wilson combat screws but they are not nearly the same quality as Challis Grips screws. I ordered a couple pair for my 1911s and they are great.

These screws look and feel well engineered. As it turns out I did not use them as they set on top of my slim Esmerelda grips rather than recessed in. My bad, I should have ordered slim screws. I will keep these for future use.
