I've never done it, but I've seen different folks over on the LCP forum that have used a punch to remove the rubber that would typically cover the laser activation button. I think the trick is to find the right size punch that makes a proper sized hole when the grip is stretched to fit over the grip. I'd start small and work up in size until I found the right size. Going too big could compromise the integrity of the grip and cause a tear. I'm not a big fan of the grip sleeves so I don't have a ton of experience with them.
