i have a Ruger 22/45 Tactical. comes with the riveted grips, so called "non-replaceable". i don't like them so-has anyone drilled out the rivets and replaced grips with Hogue rubber-finger groove grips. Hogue has them for the regular 22/45 with screws. i imagine these would have the same hole centers also. just got to pick-up a couple of screws from hardware store. this is my first blog here, just signed up, so forgive me if this is a dumb question.
