Hi,
I have a blued Mustang that I am working over and babying. I love my Lil Ponies.
Anyways, the problem is that I found some new in box Pachmayr Signature grips for the Mustang, grips from 15 or so years ago.
The problem is that the factory grip screws are just a one or two mm's too short to secure the grips. Where can I get longer grip screws for the Mustang?
I realize that too long of grip screws could impede the magazine movement in and out of the gun, so that's why I want to be careful.

I tried my google-fu, but had no luck on resolving this.

Thanks for any input.
