I like the Butler Creek square butt boot grips and have them on several K-frames, but want to tell you of another nice option besides the Spegels. Eagle Grips makes square butt "secret service" grips for the K-frame in several woods, checkered or uncheckered that are very nice and run around 50 bucks plus or minus, depending on wood and checkering. http://www.eaglegrips.com
