The grips look good on there. Simple and clean! The sear to hammer “shelves” are the only parts I’ve never messed with on ANY gun I’ve tinkered on. Maybe one day (I’d get a jig). Have not had the need to do so. I’m no competitive shooter, don’t carry a 1911 and have never met one with a trigger I did not like. Have fun with the tear down and fix up with your son. Sounds like great father/son times to me!
