I have this 1911 PC 45acp a long time and it was time to change the grips that were thick to slim ones that would look better with the slim magwell that came with the gun. I had a pair of slim ones but had to change the bushing and screws. They are not mag cut but will have to do for now. Here is a photo of the gun.

New slim magwell cut grips installed to match the slim magwell that was installed on the gun by PC when the gun was bought.

Nice! I like the new grips.
