My buddy from FL. came up to deer hunt with me and took a set of my grips back with him to install a couple of 1911 quarters in them. I think it's kinda cool but wonder how long they will stay in place under the recoil of a .45. Might put them on my RIA 9mm but feel they should go on a .45. He bought the coins and installed them for free and I like them there just wondering what you guys think. Thanks for listening.
