Wish I had found this post and Toms advice before doing mine
would have saved me maaany hours and a set or two of grips. Got it worked out though. After I drilled mine for the Hogue grip screws I used a hair dryer to soften up a Hogue handall small grip cover and slid it on to clean up where the grip screws showed (now they don't) Also, I used a few threaded ends from plastic cleaning jags to fill in the pin hole at the grips bottom which is unused in this application.
