I was unsuccessful using the factory wooden grips with hot 310gr loads on my 44mag Redhawk. Put Pachmayr Presentations on it and they were fine, so long as I had plenty of time to work into a good grip. Really fat. Unbeatable at the target range. But for speed of getting a defensive (bears) shooting grip, the Butler Creek/Uncle Mike's are the best I've tried so far. Had to round-stone off the sharp edges and the grooves and peaks till they fit. Excellent grips. Would appreciate info about other fast grips for the Redhawk. Thanks. L
