I've given up trying to contact Mac to have a pocket clip installed on one of my Mac's Custom EDC lights so I'm going to buy a clip and drill and tap the light myself. Any advise or assistance would be greatly appreciated. I have no experience in this so thanks. I would also entertain suggestions as to who you might recommend to do this for me. Thanks again.

What material is it? The only advice I can give is measure MANY times, go slowly and always think worst case.

It can be done with only a drill press & drill press vise but it's hit or miss. The easy way to do it (at least it's easy for me) is to hold the body in a Delrin split collet & secure that in an 8" super spacer on the milling machine. Locate the clip where you want it & use a fine tipped Sharpie to mark hole locations. Spot drill, tap drill, run the tap through with a small Tapmatic head, chamfer & done.

About 45 minutes if everything goes well. If things go badly you'll need to buy a replacement body & start over. BTDT.

Setup is similar to trit slot milling:
