I have used them on 1911's, and without. My personal preference is with standard thin wood grips. If the Hogues work for you, use them. They are inexpensive and easy to install. IMHO, handguns are like shoes, they MUST fit to work well. If you needed an insert to make a boot work properly....you see what I mean. And don't let fashion fool you. Sometimes the popular thing (like G10 grips) don't work well for everything.
